configure.ac: Define DEPENDS_ON_LIBINTL if LIBINTL is nonempty.

This avoids a collision between the gnulib and libintl printf wrappers.
See http://permalink.gmane.org/gmane.comp.lib.gnulib.bugs/21139 for
more information.

Thanks to Michel Boaventura for reporting the problem and to Bruno Haible
for the fix.
