Concedering that doom and thus prboom runs ok with software rendering on
any machine which will take a recent Fedora and that opengl is not
supported on all cards, I vote to compile it twice in %build both with
and without opengl, or can the current version fallback to _doom_
software rendering (not slow opengl software rendering, but the good old
isomorphic doom engine)
