I agree it is ugly. The thing is that this list of libraries is copied 
verbatim from btrfs-progs Makefile (except -lintl). I found no way to specify 
additional library dependencies.

uuid.pc does not list -lintl because this is something we add locally since 
commit a8273c4272b1b8 (util-linux: fix libintl linking if present). Yann has 
proposed a patch (http://patchwork.ozlabs.org/patch/416000/) adding -lintl to 
uuid.pc when applicable. We'll still need to repeat the rest of the list,
something like:

	lib_LIBS="-luuid -lblkid -lm -lz -llzo2 -L. $(shell pkg-config ...)"

so I'm not sure it buy us much.
