Yep, strnchr.

Not sure what it has to do with that. The #ifdef __HAVE_ARCH_* stuff 
is that architectures with crazy enough hackers can add assembly
optimized functions if they want. But it clearly doesn't make any sense
with this function (in fact it doesn't make much sense with any string
function except memset/memcpy), so better not encourage it.
