I like to be able to look up lzlib via pkg-config, I searched the mailing list
and found that others want it too. So here are patches that make this work.
The install-pc target is not run by default, I leave it up to Antonio to decide
if the pkg-config file should be installed automatically or if install-pc has to
be run separately.
