It needs to do resolution, so for example you might have a machine
specific library you'd expect the code to find it first, then
architecture specific and finally all arch only if the others don't work
out.

Having said that, I've had thoughts about making this just look at
machine, package_arch and allarch, not everything. It also gets more
complicated with multilibs.

It may be the different callers might need to specify more about what
exactly they're after as they may want different things.

Cheers,
