Just the arch-specific code for now. It will just make these like RC4
and MD4 which are still implemented for compatibility reasons but only
with generic C code. Someday (years from now) we should remove all of
these entirely, but for now the best we can hope for is simplifying the
implementations to just the generic C code.
