Linux kernel compilation for aarch64 triggers ICE if

The rootcause is GCC bug #91102 'aarch64 ICE on Linux kernel with -Os'.

If the OS is not Linux, the code could end up generating a recursive symlink.
This can happen because the same symlink can be created twice in a row. If this
happenes, the second symlink becomes a link to itself within the directory
pointed to by the original link.
In order to prevent this, verify that the destination does not already exist.

Without relocating PREFIX/EXEC_PREFIX the system can not do runtime
relocation for the path to the usr/lib/gcc directory, and other components.
While this is not a normal or supported use-case it does work in the upstream
gcc. This is difficult to test with the regular OE SDKs, as it requires
running the components with the correct LD_LIBRARY_PATH and ld.so.
Without this update, gcc will typically not be able to find the gcc
provided include file for stddef.h and similar. This is due to certain
relocations being based on the PREFIX and/or EXEC_PREFIX locations which
are hardcoded at compilation time.

suites. The component test suites require execution of compiled programs
on the target.
The implementation provided allows for execution testing against a host
via SSH or within the local build environment using qemu linux-user
execution. The selection of execution is done via the
TOOLCHAIN_TEST_TARGET variable, and configuration of the remote host is
done with the TOOLCHAIN_TEST_HOST, TOOLCHAIN_TEST_HOST_USER and
TOOLCHAIN_TEST_HOST_PORT variables.
By default the do_check task will execute all check targets, this can be
changed by setting MAKE_CHECK_TARGETS to the desired test suite target
(e.g. check-gcc or check-target-libatomic).

We had interesting failures where building gcc-cross-powerpc with 5.0 kernel
headers, then building eudev after moving to 5.2 headers failed.
gcc-cross doesn't rebuild when linux-libc-headers changes due to its
listing in SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS. This shouldn't matter but
fixincludes as adding asm-generic/socket.h to its filtered list which
was then replacing the real header with an older version. This mismatch
lead to build failures.
We trust the Linux kernel headers to be ANSI safe so lets just clear out
any headers and trust the originals to be correct.

We've since had many changes to pkgdata including separating it

OE does not use the traditional /usr/lib/gcc prefix to store gcc-runtime
it basically is moved into libdir, however some newer files were
installed by newer versions of gcc especially libgomp ( omp.h openacc.h )
into gcclibdir, so we have content in both directories, this confuses
other tools which are trying to guess the gcc installation and its
runtime location, since now we have two directories, the tools either
choose one or other and we get inconsistent behavior, e.g. clang for
aarch64 uses /usr/lib but same clang for riscv64 chose /usr/lib/gcc
This change ensures that OE ends up with single valid location for gcc
runtime files

The SDK was unable to find the C++ header pieces correctly since it's
using a generic compiler, not one specifically targeting the multilib
vendor prefix and default tune. This adds the right mapping to ensure
SDKs work as expected. And fix problem in below configurations:
multilib configuration 1:
MACHINE="qemumips64"
MULTILIBS ?= "multilib:lib32 multilib:libn32"
DEFAULTTUNE_virtclass-multilib-lib32 ?= "mips"
DEFAULTTUNE_virtclass-multilib-libn32 ?= "mips64-n32"
MULTILIB_GLOBAL_VARIANTS_append = " libn32"
require conf/multilib.conf
ignoring nonexistent directory "<path>/sysroots/mips64-poky-linux/usr/include/c++/8.2.0/mips64-poky-linux/32
multilib configuration 2:

MULTILIBS = 'multilib:lib64 multilib:lib32'
DEFAULTTUNE = 'mips64-n32'
DEFAULTTUNE_virtclass-multilib-lib64 = 'mips64'
DEFAULTTUNE_virtclass-multilib-lib32 = 'mips32r2'
require conf/multilib.conf
For this configuration:
for target gcc-runtime, need to create symlink like mips64-poly-linux --> mips64-poky-linux-gnu32
for target lib64-gcc-runtime, need to create symlink like mips64-poly-linux/32 --> mips64-pokymllib64-linux
in order to avoid conflict during populate_sdk, create symlink for subfoler bits/ext for target gcc-runtime,
this is ugly, but seems no better way to cover all kinds of configuration.

MACHINE="qemumips64"
DEFAULTTUNE = "mips64-n32"
