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

In 003dd05e4c168f7c3cccb9cbfad3fd8f38fe8741, clang replaced the oe-core
provided llvm for building mesa. However, mesa needs AMDGPU to be
enabled on the native target in order to build. Following the example
of oe-core's recipe, just enable AMDGPU for all targets.

This helps in deciding on linking libatomic, therefore its important to
check for atomic<double> because on x86, clang decides to not use
built-in whereas gcc does, so clangd e.g. links ok when using gcc but
fails when using clang with gcc-runtime on x86

When using meta-clang, it makes sense to use llvm provided by clang
recipe, this ensures that we do not build llvm from oe-core but instead
offer the one from clang recipe
enable rtti and eh for native/nativesdk clang, this is needed for mesa
to build
Let clang PROVIDE llvm
Build AMDGNU and other targets, this is needed for llvm-config to work
properly, since we use llvm-config from clang-native, so its better to
build the targets that are built for clang-native atleast
create version specific symlinks for tblgen anf llvm-config

libunwind can be either nongnu libunwind ( from OE-Core ) or from llvm
and when using clang and using --unwindlib=libunwind we know we have to
use llvm libunwind implementation, so remove libunwind from DEPENDS and
add llvm-libunwind to depends
Drop providing libunwind from llvm-libunwind since its not needed
anymore
