It seems odd to call the variant 'system_x11' in those cases, since
they're not necessarily used as part of X11 at all. Would it be more
appropriate to change the dependents that use them with X11?

I admit I haven't looked into it enough to know if there would be
problems either way.

BTW, does all this mean that we should be mass-changing lib:libX11:blah
deps to port:xorg-libX11? (Or a different port?)
