So, while theoretically it's true that libgd2-xpm should not be linked
directly to libX11 (configure.ac could be modified, but then pkg-config
could not be used), in effect it does not matter much for php5-gd, as
the end result is the same as long as it keeps linking against libgd2-xpm
instead of libgd2-noxpm:
