For static builds we need to better track the dependencies of drivers,
because, unlike with shared libs, the static libs don't track them
themselves. Because of this we have a new global list of external
dependencies which is used for creating the pkg-config file. We also move
the logic for what dependencies a driver has, and if those deps are met,
from the higher level build file to the drivers themselves.
