IMHO, it's OK to leave it per port basis, rather than per cpu.
That's the reason why crunchgen was modified to have -d option,
and not all ports have size restriction.

I don't know if there are any side effects around -mmemcpy,
but if it works fine in any situation on mips, it should be
enabled by the compiler if -Os is specified.

(IIRC current gcc enables -mmultiple on powerpc if -Os is specified,
 though our in-tree gcc doesn't.)
