Note that's dep:foo,bar; not a bare "allow any use flags to be OR'd 
together".  In light of the fact it *is* just an expansion hack, the 
usage is semi limited although there are scenarios for it; arches, 
namely (if amd64 or x86, use this, if mips, that, etc).

I have no preference either way; extending it outside of dep isn't 
necessary if people hate it, although as said, there are some 
potential uses for it.

That said, if we were to start using it, the ',' as an 'or' operator 
mildly sucks; dep:build|run also sucks (hard to read), and 
dep:build+run, to me at least, implies 'and'.  And yep, bikeshedding 
potential there.
