More gnubg

So, while some of my other changes to this package were still worthwhile, the fix to link against libsupc++ didn't fix the build failures on hppa and m68k. Still all the same unwind and gxx_personality symbols are missing. I'll have to do more poking.

Also, the AMD64 crash appears to be inside Guile somewhere. Suggestion: disable Guile. Well... I can do that, but that sucks. There have actually been requests for that functionality. I don't want to just turn it off and not try to figure out what's wrong. Ugh.

Other than that, a scattered but not too bad day in which I learned more about managing our DNS servers and learned far more about Alsa and udev than I wanted to know.
