I was looking at these a few weeks ago as well...  the loop unrolling
done in some of the string operations is silly to do on m68k cpu32
variants, since they have a loop mode.  I imagine other architectures
are similar.

maybe some of these could be moved to libgloss for the architecture-
specific implementations?
