Great.  If you can rewrite _all_ the regular, non-pkg makefiles to use
that construct, instead of the .if tests with an explicit list of
architectures -- like

if (${MACHINE} == "alpha") || (${MACHINE_ARCH} == "mips") 


and find _one_ place to fixup the arch/mips subdir walk, and fix
makeflist, I'm happy. I dont quite see how to do that with
ONLY_FOR_ARCHES, at least not more than once more than once per
Makefile, but maybe I'm thick.  I still think it's better to define a
variable that means ``mips arch of any kind''.

It still doesn't address the point that some arch's logicall imply
others (a package for mipseb should be runnable on mipseb64, possibly
with a 32-bit emul package as a prereq) but that's true either way.
