It seems GCC may not end up sticking with `-fextra-libc-function=`. They seem to want to do this
just with just a check for if `__memcmpeq` is declared.

Assuming GCC does stick with `-fextra-libc-function=` do you think llvm's side should keep the 
`--with-builtin-memcmpeq` and clang should enable that if it sees '__memcmpeq' in 
`-fextra-libc-function=*` or it should redirect all extra functions to llvm and let llvm handle them?
