I don't see what you are trying to achieve here. Why shouldn't the
command fail if it is not the intended way to call it? There are a
couple of use cases where drivers/ is used to share common code over
different archs and it is not always the intention to build them in
drivers/ directly.

If a list is the intention here, aren't there other ways to create it
other than using drivers/*?
