One further idea I sort of like:

-include arch/$(ARCH)/subarchs.mak

and coming up with a halfway-clean way, in subarchs.mak, to put rules
that override the asm files that get used for particular modules.
However, I'm not seeing a really clean way to do that. I don't want to
end up duplicating the commands for assembling into files other than
the main makefile.
