Confirmed. I never heard about that config - at the time I tried it on an old
system with GCC4.8 and that built and passed all tests. I can't see a reason to
ever switch off ifuncs...
The !HAVE_IFUNC case needs to also define IFUNC_ALT 1 and atomic_16.S must add
aliases to __atomic_load_16 etc. Then it works fine. I'll send a patch.
