The ordering here is wrong.  -luuid must come after UUID.o on the
command line if the linker is to resolve uuid_* symbols in UUID.o from
the -luuid library.

With standard autoconf this is achieved by the convention that -l
arguments must go in LIBS not LDFLAGS.  I don't know if the perl system
uses the same convention, but whatever it uses, the -luuid argument does
not belong where it's currently being set.
