To be honest, I started rewriting multilib-strict to be sane but lost
motivation pretty early. Feel free to take it up, it shouldn't be hard.
Just horribly boring.

Basically, it should iterate over all ABIs, get libdirs for them
and look for libraries *directly* in those libdirs. Anything below first
level can be ignored as unclear with a good hit rate anyway.
