That is to say, this problem doesn't exist with toolchain using recent
libc. However, this link error still exists when an old toolchain is
used and it sounds unfeasible to upgrade libc to fix the link error.
Link -lmachuser and -lhurduser explicitly, as a fallback, is no harm.

I don't have a strong opinion on this patch.

Yes.
