Thing is, farsight2 shouldn't care at all about libuuid. It is net/gupnp's
problem - so why have this in gupnp's buildlink3.mk at all?
(Hence "what problem is this trying to fix?")

Part 2 is whether gnupnp needs to do extra work vis-a-vis libuuid.pc, or
whether this means libuuid/builtin.mk needs attention.
