I suspect that if any ${ARCH} == "arm" type stuff exists in ports it
may need evaluation to see if the intent, and thus the fix, was really
somthing like ${ARCH:Marm*}.

I suspect there are relatively few occurances of bare "arm" that don't
really need to apply to all arm arches, except in places where the
other arm arches are also handled nearby.
