[PATCH] mesa-gl: The purpose of mesa-gl is to provide for X11 usage

["Mark Hatle" <mark.hatle@kernel.crashing.org>]

Trying to build mesa-gl without X11 enabled, results in numerous errors
about being incorrectly configured, such as:

  ERROR: Problem encountered: building dri drivers require at least one windowing system or classic osmesa

After consulting with the author of this recipe, it was clear that it
was only intended for the X11 use-case, so requring X11 should avoid the
error message above.
