This will disable many reverse dependencies. If you need your program to work
you will need to migrate it to the newer gstreamer package.

This seems to have been confusing people, using both xlibs and xorg, etc.
- Avoided renaming local (and different) xlibs binding in gcc*.
- Fixed cases where both xorg and xlibs were used.
Hopefully everything still works as before.
It was really ugly that `xlibs.xlibs` meant something else than `xlibs`,
especially when using `with xlibs`, such as in wine.
Also, now `xlibs` is the same as `xorg`.
