I'd say the eventual amount of packages that would use such a build
system are between 5-10. Should I go ahead and make a dpf-build-system
or do you think we should just copy the code around since it's not that
many packages?

By the way, we used inheritance in the case of other packages such as
gx-* and vl1-emulator/regrader/fogpad, although those are from the same
upstream so maybe it's reasonable there.
