Mesa fails to make an indirect rendering context current and freezes
in the next X11 call.

Removing indirect rendering support seems like a workaround for the
problem, but realisticly it's no longer interesting what indirect
rendering provides if direct rendering is available. If direct
rendering is not available, it will pick indirect instead.
