This is being worked on, together with at least making ia64 work as
well, possibly other architectures as well.  Neither kwm nor me (the two
of us who does the heavy lifting) has access to anything other than x86
and x86_64, so it's slightly slow going.

Why is this needed?  Shouldn't ${MACHINE_CPU:Mmmx} and
${MACHINE_CPU:Msse2} be undefined for CPUs (including ppc) that don't
have mmx or sse2?  This should prevent mmx and sse2 from being used at
all.  Or am I misunderstanding the issue here?
Regards!
