pigz, which stands for parallel implementation of gzip, is a
fully functional replacement for gzip that exploits multiple
processors and multiple cores to the hilt when compressing data.
do_package uses pigz to compress data to speed up the time
if there is pigz available on the build server.
But for some big package such as clang, there comes below
error during do_package.
gzip: stdout: Cannot allocate memory
tar: TOPDIR/sstate-cache/20/80/sstate:clang:cortexa57-wrs-linux:10.0.1:r0:cortexa57:3:20808f8a746b00ec9470a81057c8595d878cfe8c565cfbcbbaa3ea870528ee34_package.tgz.QF5dss8M: Wrote only 8192 of 10240 bytes
tar: Child returned status 1
tar: Error is not recoverable: exiting now
So set the default pigz thread for clang and the user also can
customize the pigz thread such as PIGZ_pn-clang = "-p 3" for
clang in local.conf to avoid eating so much memory.

a choice is needed to be made for selecting unwinder library defaults (
--unwindlib ), by default we choose libgcc unwinder when packageconfig
is disabled and only use llvm unwinder when this option is enabled

libcxx can use either libgcc_s or llvm libunwind for unwinder
functionality, the defaults are platform dependent, therefore with this
patch we make intentional choice based on RUNTIME settings chosen, e.g.
when using GNU runtime we use libgcc and also ensure that it add right
compiler options to build as well, since libcxx build looks C runtime by
calling $($CC --print-libgcc-file-name) to build libc++abi.so unless we
use right -rtlib option it will result in linking wrong library
Enable RTTI as well
do not enable llvm unwinder unless we chose llvm runtime, even that
might not work since libpthread from glibc explicitly dlopens
libgcc_s.so to enable unwinding

* issue:
the openembedded-core build procedure relies on changed default
dynamic loader path when the usrmerge distro feature turned on.
As we can find the GCC which is used as default toolchain uses
SYSTEMLIBS_DIR macro variable set to /usr/(lib|lib64) at build
time and hardcodes the binaries with that default loader path.
* solution:
change the default dynamic loader location with --dyld-prefix
clang option to conform the loader location (as GCC does) to
openembedded-core build procedure.

* Commit 1ce5b0090e18 ("clang: Search for dynamic linker.") does not
honor --dyld-prefix option, so it fails to find the linker when --dyld-
prefix is used for usrmerge. Add DyldPrefix when searching for dynamic
linker.

By default, clang looks for resourses relative to the binary location:
${location}/../lib/clang/${version}/
However, the default bindir defined in cross.bbclass is a subdirectory of bin,
so clang forms a directory that looks like /usr/bin/lib/clang/10.0.0/
Apply a patch to use ${location}/../../lib/clang/${version} if the directory
name of ${location}/.. is "bin".
