Comment (by Ionic):

 Yeah, must be muniversal being thrown off by that, for whatever reason.
 Probably because it defines its own universal variant that we're now
 overriding wrongly.

 The approach is flawed anyway, since OpenGL functionality is not always
 enabled even if universal requires x11. Older platforms won't have support
 for OpenGL if built -universal-x11, which means that gstreamer1-gst-
 plugins-bad will still fail.

 I guess I'll have to create an opengl variant that requires either x11 or
 nothing (meaning cocoa, if supported, i.e., if the OS is new enough).
 Ugly, but I don't see a better way.
