[compiler-rt][x86] assert.h not found when trying to build builtins without a libc

[quic-k]

I am trying to build compiler-rt builtins for x86-64 without a libc
job link

the assert.h include and its uses should probably be guarded by #if defined(__linux__)

the include line and assert calls

I can push a patch if the above sounds fine
