AFAIK i386 has not been supported for Linux configurations since the advent
of NPTL. AIUI i386 per se supports exactly one SMP-safe operation, which
is xchg. Reworking everything to work with just that is conceivable, but
it doesn't seem worth the effort.
i386 has always and AFAIK still works for Hurd configurations. But I don't
think there is any particular reason we care to support < i486. If anybody
really has chips that old still in use, they can show up and do the work.
