The problem is it wasn't the case for gtk-doc.m4 serial 1, the check and
need for pkgconfig is done after gtk-doc is enabled, but for serial 2
some of the checks are done before that.
So we'd need to find all packages that use gtk-doc.m4 and add it there
(well, for those that autoreconf, but that would be sloppy since an
added autoreconf would trigger the need).
As stated i prefer to keep it simple without patching gtk-doc.m4 for
when serial 3 comes around.
Regards.
