Sean Christopherson 7cf2e7373a KVM: selftests: Explicitly disable builtins for mem*() overrides 
Explicitly disable the compiler's builtin memcmp(), memcpy(), and
memset().  Because only lib/string_override.c is built with -ffreestanding,
the compiler reserves the right to do what it wants and can try to link the
non-freestanding code to its own crud.

  /usr/bin/x86_64-linux-gnu-ld: /lib/x86_64-linux-gnu/libc.a(memcmp.o): in function `memcmp_ifunc':
  (.text+0x0): multiple definition of `memcmp'; tools/testing/selftests/kvm/lib/string_override.o:
  tools/testing/selftests/kvm/lib/string_override.c:15: first defined here
  clang: error: linker command failed with exit code 1 (use -v to see invocation)

Fixes: 6b6f71484b ("KVM: selftests: Implement memcmp(), memcpy(), and memset() for guest use")
