We've removed all of the #ifdef code inside Mesa that would have made 
any difference.  It was a nightmare to maintain, and we almost always 
got it wrong... because nobody was testing that configuration.  The only 
thing this is possibly going to gain you is a trivial amount of build 
time (by not building libGL, etc.).
