  [libc] Use LTO for AMDGPU compilation and linking

Summary:
The AMDGPU ABI isn't stable or well defined. For that reson we prefer to
rely on LTO to ensure that multiple files get linked correctly.
Currently the internal targets used for testing mix LLVM-IR and
assembly. We should be consistent here.
