gcc: Update patches submitted/merged upstream

I took 5 of our patches and submitted to upstream gcc. This highlighted that
patches 0026 and 0018 should be merged together and some tweaks were made to
try and make it acceptable to upstream. The other patches have their headers
updated to match what was submitted.

The libstdc++ option patch was also cleaned up ready for upstream as the
documentation wasn't quite right.

The CXXFLAGS_FOR_BUILD piece of 0026 is separated out into a new patch which
can be submitted separately to upstream.

Two of the patches have been merged, status updated accordinly.

(From OE-Core rev: df9b8ec56ff29f14feb1fde6acbdf9c4667430cf)

+Subject: [PATCH 5/5] gcc: Pass sysroot options to cpp for preprocessed source
 
-Currently, if the gcc toolchain is relocated and installed from sstate, then you try and compile
-preprocessed source (.i or .ii files), the compiler will try and access the builtin sysroot location
-rather than the --sysroot option specified on the commandline. If access to that directory is
-permission denied (unreadable), gcc will error.
+OpenEmbedded/Yocto Project extensively uses the --sysroot support within gcc.
+We discovered that when compiling preprocessed source (.i or .ii files), the
+compiler will try and access the builtin sysroot location rather than the
+--sysroot option specified on the commandline. If access to that directory is
+permission denied (unreadable), gcc will error. This is particularly problematic
+when ccache is involved.
 
-This happens when ccache is in use due to the fact it uses preprocessed source files.
+This patch adds %I to the cpp-output spec macro so the default substitutions for
+-iprefix, -isystem, -isysroot happen and the correct sysroot is used.

-Subject: [PATCH] gcc: Fix argument list too long error.
+From: Richard Purdie <richard.purdie@linuxfoundation.org>
+Subject: [PATCH 2/5] gcc: Fix "argument list too long" from install-plugins
 
-There would be an "Argument list too long" error when the
-build directory is longer than 200, this is caused by:
+When building in longer build paths (200+ characters), the
+"echo $(PLUGIN_HEADERS)" from the install-plugins target would cause an
+"argument list too long error" on some systems.
 
-headers=`echo $(PLUGIN_HEADERS) | tr ' ' '\012' | sort -u`
+Avoid this by calling make's sort function on the list which removes
+duplicates and stops the overflow from reaching the echo command.
+The original sort is left to handle the the .h and .def files.
 
-The PLUGIN_HEADERS is too long before sort, so the "echo" can't handle
-it, use the $(sort list) of GNU make which can handle the too long list
-would fix the problem, the header would be short enough after sorted.
-The "tr ' ' '\012'" was used for translating the space to "\n", the
-$(sort list) doesn't need this.

-The OE environment sets and exports CPP as being the target gcc. When
-building gcc-cross-canadian for a mingw targetted sdk, the following can be found
-in build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log:

+Subject: [PATCH 1/5] Makefile.in: Ensure build CPP/CPPFLAGS is used for build targets
+
+During cross compiling, CPP is being set to the target compiler even for
+build targets. As an example, when building a cross compiler targetting
+mingw, the config.log for libiberty in
+build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log
+shows:
+
 configure:3786: checking how to run the C preprocessor
-configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32
-configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c
+configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=[sysroot]/x86_64-nativesdk-mingw32-pokysdk-mingw32
+configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=[sysroot]/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c
 configure:3876: $? = 0
 
-Note this is a *build* target (in build-x86_64-linux) so it should be
-using the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32
-headers are very different, using the wrong cpp is a real problem. It is leaking
-into configure through the CPP variable. Ultimately this leads to build
-failures related to not being able to include a process.h file for pem-unix.c.
+This is libiberty being built for the build environment, not the target one
+(i.e. in build-x86_64-linux). As such it should be using the build environment's
+gcc and not the target one. In the mingw case the system headers are quite
+different leading to build failures related to not being able to include a
+process.h file for pem-unix.c.
+
+Further analysis shows the same issue occuring for CPPFLAGS too.
+
+Fix this by adding support for CPP_FOR_BUILD and CPPFLAGS_FOR_BUILD which
+for example, avoids mixing the mingw headers for host binaries on linux
+systems.
+
+2021-10-27 Richard Purdie <richard.purdie@linuxfoundation.org>
+
+ChangeLog:
 
-The fix is to ensure we export a sane CPP value into the build
-environment when using build targets. We could define a CPP_FOR_BUILD value which may be
-the version which needs to be upstreamed but for now, this fix is good enough to
-avoid the problem.

-Subject: [PATCH] Fix various _FOR_BUILD and related variables
-
-When doing a FOR_BUILD thing, you have to override CFLAGS with
-CFLAGS_FOR_BUILD. And if you use C++, you also have to override
-CXXFLAGS with CXXFLAGS_FOR_BUILD.
-Without this, when building for mingw, you end up trying to use
-the mingw headers for a host build.
-
-The same goes for other variables as well, such as CPPFLAGS,
-CPP, and GMPINC.
