SVGAlib, X, GL, SDL, and GLIDE. Modified the Makefile.am's to match the new configure variables. Now people don't have to manually hack src/Makefile.am to build their targets. - Fixed a typo in src/qgl.h with the #define - Added new automake generated files to bootstrap's clean command. - Added build requirements to HACKING, as we now need automake 1.6. - Removed note in README about the asm FPE bug, as I seem to have inadvertently fixed this without meaning to.
