+Quote from bug 1443 which explains what the patch does : 
+  We build some random program and link it with -lust.  When we run it,
+  it dies with a SIGSEGV before reaching main().
+  
+  Libust.so depends on liburcu-bp.so from the usermode-rcu package.
+  Although libust.so is not prelinked, liburcu-bp.so IS prelinked; this
+  is critical.
+  
+  Libust.so uses a TLS / __thread variable that is defined in liburcu-
+  bp.so.  There are special ARM-specific relocation types that allow two
+  shared libraries to share thread-specific data.  This is critical too.
+  
+  One more critical issue: although liburcu-bp.so is prelinked, we can't
+  load it at its prelinked address, because we also link against
+  librt.so, and librt.so uses that address.
+  
+  The dynamic linker is forced to relink liburcu-bp.so at a different
+  address.  In the course of relinking, it processes the special ARM
+  relocation record mentioned above.  The prelinker has already filled
+  in the information, which is a short offset into a table of thread-
+  specific data that is allocated per-thread for each library that uses
+  TLS.  Because the normal behavior of a relocation is to add the symbol
+  value to an addend stored at the address being relocated, we end up
+  adding the short offset to itself, doubling it.
+  
+  Now we have an awkward situation.  The libust.so library doesn't know
+  about the addend, so its TLS data for this element is correct.  The
+  liburcu-bp.so library has a different offset for the element.  When we
+  go to initialize the element for the first time in liburcu-bp.so, we
+  write the address of the result at the doubled (broken) offset.
+  Later, when we refer to the address from libust.so, we check the value
+  at the correct offset, but it's NULL, so we eat hot SIGSEGV.

+Upstream-Status: Pending
+Signed-off-by: Khem
+Hi,
+This patch adds 'make menuconfig' support to EGLIBC.
+EGLIBC can re-use the Linux kernel kconfig host tools ('conf' and 'mconf') unmodified, by passing appropriate environment variables and with some pre- and post-processing on the input/output config files.
+There are three new make targets supported, which all are defined in the new libc/options-config/Makefile, which is included by the top-level libc/Makefile:
+- 'make defconfig'. This passes 'libc/option-groups.defaults' to 'conf' as a default config, and outputs 'option-groups.config' to the top-level build directory, which will be the same as the default config.
+- 'make config'. This is the same line-oriented interface as in the Linux kernel. Input and output is 'option-groups.config' in the top-level build directory.
+- 'make menuconfig'. This is the same menu-based interface as in the Linux kernel. Input and output is 'option-groups.config' in the top-level build directory.
+Pre-Processing:
+The Linux kernel kconfig tools expect a prefix of "CONFIG_" on all config option names, but EGLIBC expects a prefix of "OPTION_". The pre-processing script, libc/options-config/config-preproc.pl, simply replaces "CONFIG_ with "OPTION_" in the given config file. The libc/options-config/Makefile passes the script output to a temporary config file, which is then passed to 'conf' or 'mconf'.
+Post-Processing (libc/options-config/config-postproc.pl):
+- Disabled options are output as a comment line of the form "# CONFIG_FOO is not set". This needs to be changed to an explicit "CONFIG_FOO=n" in order to be compatible with 'option-groups.awk' which generates the option-groups.h header.
+- "CONFIG_" prefix is changed back to "OPTION_".
+- The kconfig tools will not output anything for options that depend on a parent option, when the parent option is disabled. This implicit disable must be converted to an explicit "CONFIG_FOO=n" in order to be compatible with the way EGLIBC overrides the default option settings in 'libc/option-groups.defaults' with those in 'option-groups.config'.
+A new configure option, '--with-kconfig=<PATH>', tells EGLIBC where to find the pre-built 'conf' and 'mconf' host tools from Linux kernel builds.
+libc/EGLIBC.cross-building is updated to include instructions for using '--with-kconfig' for the final EGLIBC build, and shows how and when to run 'make *config'.
+libc/EGLIBC.option-groups is updated to include new information on the menuconfig support.
+Thanks,
+attached is the updated patch to address above issues.

+Note the additional '--with-kconfig' option. This tells EGLIBC where to
+find the host config tools used by the kernel 'make config' and 'make
+menuconfig'.  These tools can be re-used by EGLIBC for its own 'make
+*config' support, which will create 'option-groups.config' for you.
+But first make sure those tools have been built by running some
+dummy 'make *config' calls in the kernel directory:
+
+    $ cd $obj/linux

+    $ PATH=$tools/bin:$PATH make menuconfig \

+Subject: [PATCH] eglibc: run libm-err-tab.pl with specific dirs in ${S}
+libm-err-tab.pl will parse all the files named "libm-test-ulps"
+in the given dir recursively. To avoid parsing the one in
+${S}/.pc/ (it does exist after eglibc adds aarch64 support,
+${S}/.pc/aarch64-0001-glibc-fsf-v1-eaf6f205.patch/ports/sysdeps/
+aarch64/libm-test-ulps), run libm-err-tab.pl with specific dirs
+in ${S}.

+This patch builds on the menuconfig patch for EGLIBC.
+There are a few options that have non-boolean types, that would benefit from the new 'make *config' support:
+EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE (int)
+EGLIBC_NSSWITCH_FIXED_CONFIG (string)
+EGLIBC_NSSWITCH_FIXED_FUNCTIONS (string)
+The patch converts these to real options in libc/option-groups.def. Also, libc/scripts/option-groups.awk is modified to output a '#define' line for int, hex, or string options encountered in the config file.
+In the post-processing script config-postproc.pl, a small change is needed: for any boolean option FOO that is implicitly disabled in the kconfig output, make sure that option is indeed a boolean before printing the explicit OPTION_FOO=n.
+Finally, libc/malloc/Makefile passes __OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE as a CPPFLAGS, which is not necessary anymore because this macro will now be present in the generated header.
+attached is the updated patch to address above issues.

+As part of the menuconfig development, I encountered some outdated information in the cross-build instructions, libc/EGLIBC.cross-building. This patch updates the file with new (and tested) instructions. It is unrelated to the menuconfig support, but applies after.
+My testing was done with an ARM target, and an x86_64 Linux host, so I converted the instructions to use those host/target types from the original i686/powerpc. Hope that's ok.

+The default lib search path order is:
+  1) LD_LIBRARY_PATH
+  2) RPATH from the binary
+  3) ld.so.cache
+  4) default search paths embedded in the linker
+For nativesdk binaries which are being used alongside binaries on a host system, we 
+need the search paths to firstly search the shipped nativesdk libs but then also
+cover the host system. For example we want the host system's libGL and this may be
+in a non-standard location like /usr/lib/mesa. The only place the location is know 
+about is in the ld.so.cache of the host system.
+Since nativesdk has a simple structure and doesn't need to use a cache itself, we 
+repurpose the cache for use as a last resort in finding host system binaries. This 
+means we need to switch the order of 3 and 4 above to make this work effectively.

+Upstream-Status: Inappropriate [SDK specific]
+This patch puts the dynamic loader path in the binaries, SYSTEM_DIRS strings
+and lengths as well as ld.so.cache path in the dynamic loader to specific
+sections in memory. The sections that contain paths have been allocated a 4096
+byte section, which is the maximum path length in linux. This will allow the
+relocating script to parse the ELF binary, detect the section and easily replace
+the strings in a certain path.

+eglibc-nativesdk: Fix buffer overrun with a relocated SDK
+When ld-linux-*.so.2 is relocated to a path that is longer than the
+original fixed location, the dynamic loader will crash in open_path
+because it implicitly assumes that max_dirnamelen is a fixed size that
+never changes.
+The allocated buffer will not be large enough to contain the directory

+Upstream-Status: Inappropriate [embedded specific]
+The native version of ldconfig was using native definition of LD_SO (i.e. 
+ld-linux-x86-64.so.2 ) which is not correct for doing the cross ldconfig.
+This was causing libc.so on the target marked as ELF lib rather than 
+FLAG_ELF_LIBC6 in the ld.so.cache.
