Today with "auto" you'll get some error message if a driver cannot be
built because of a missing library, right?
What happens after your patch? Is the user informed that some driver
included in the "auto" set is not going to be built because of a
missing library? It doesn't seem like it, unless I'm missing
something, and that seems potentially worse than giving an error.
I think automatic selection of build targets really breaks down when
you have as many options and dependencies as we have.
