I had another think about this..

What about if devel/pkgconfig is modified to search in /usr/libdata/pkgconfig and systems with native libusb have entries in there?
eg..

Along with..

Ports will still need code to know 8.x+ do not require libusb but they need that regardless.

I'm not sure what the "right way" to install such files in libdata is though.
