No, just:

darwin/ppc
darwin/x86
darwin/10.4/ppc
darwin/10.4/x86
darwin/10.5/ppc
darwin/10.5/x86

Well, that's just doing it the other way around?

Hmmm... not sure if other profiles are much in need for it.  Alternative
is to create a prefix/arch/{x86,ppc,sparc,...}, or maybe even start
inheriting arch/X.  In principle looks ok, but its linux biased
sometimes...
