I can hack the .c code to define it, and I see sidebyside and anaglyph rendering work well, toggled by the statsbarHud options page. I know little about the linux build system.

Curious -- is there any particular need for this to ever be off?  Or are
we using compile-time #ifdefs to do something that should probably be
configured at runtime?
