Makefile: allow linker override for cross uuid test

The test to determine whether libuuid is installed uses the host 'ld' utility.
This breaks when cross compiling, since target libraries are often different
than host libraries.

Use $(LD) instead. This allows to easily use the cross compiler linker.
