Those are for macros generated inside `%%public_api` block, similar to: https://github.com/llvm/llvm-project/blob/main/libc/config/linux/api.td#L30

Since we put all of their generic definitions in `stdfix-macros.h` to be used by internal implementations, they are not needed here.  Otherwise, it will create redefinitions of those macros.
