[Cin]Sparc32 "support"

Not really, but it compiled to completion, and shwed startup messages and died in GL library call (inside GL library, mesa) :) So, trying to rebuild on netBSD/sparc with opengl disabled Not even diffs, just bootstrap.c and Makefile from guicast folder. Need more ram on compile machine, 256 M too small with 32 Mb of swap for affine.c :)
