PATCH: warn if libgdbm linked

[Peter Stephenson <pws@xxxxxxx>]

This is following a discussion off-list.  Linking against libgdbm in the
binary means it's covered by the GNU General Public License (even if the
binary only contains bindings to the shared library and not the code,
apparently), so it might be safer to warn that this has happened.  As
we're not using any GNU code in the source, it's not affected.
