is udevdir to be retired? iirc HAL never exported this as a variable
hence the hardcoded path, but I think relying on the udev package to tell
you where to look for data is the correct approach.

your patch has two changes: remove udev pkgconfig bits and change the
default. I agree with the latter, it seems the right thing to do, but not
the former.
