[Bug-gnubg] GL build on a non-GL system

[Russ Allbery]

(I've also submitted this as bug 19678 on Savannah.)

If gnubg is built with GL support, the binary can't even be started on a
system that doesn't have GL. This is less than ideal for a build for a
Linux distribution (such as Debian).

Would it be possible to try to initialize GL and, if it failed, fall back
on the 2D board behavior as if GL were not compiled in? This way, the same
binary could be used with GL-enabled systems and systems that only have
non-GL X.

Thanks!
