permit linking to libudev , needed for Controller Support in godot engine

[poetaster]

As @sashikknox asks here: https://forum.sailfishos.org/t/harbour-is-libudev-really-need-to-be-depricated-in-harbour/13304

I'm also interested (well, doing it already) in getting more people behind doing godot on SFOS. It's a fairly low barrier to entry for game development.

As the forum posts makes clear, the work-a-rounds are a burden and linking for device support should be reasonable?
