clang: Do not build all native targets for target as well

Just build BPF and AMDGPU (needed by mesa) when building target clang
along with the target arch

Pass  -DNDEBUG -g0 to CXXFLAGS to strip debug info, current amount of
debug info is is humungous ( even with -g1 ) some binaries are > 1G
in size, it takes a long time to link them and also package them since
we have a strip debug info step which takes forever

This should speedup clang build significantly
