I know Apple doesn't want you to run their OS on non-Apple hardware,
but I don't think we should reinforce that standpoint. Could we just
match *-*-darwin*?
I agree.
Also, I'm a bit confused by the Darwin vs. MacOS X naming game. I
realize it would be quite a bit of work, but to me it would make sense
to exclusively use Darwin in comments, function names and file names
(appropriately capitalized).
Yes, we should be using "Darwin" everywhere in sources, file names, etc. "Mac OS X" refers to the total package that Apple delivers, with Aqua, Finder, etc, while Darwin is kernel + Unix-style tools. Darwin is fully functional by itself, and to the casual user would look nearly identical to FreeBSD. There shouldn't be anything in FSF GDB that depends on non-Darwin OS X bits; there wasn't anything like that in Apple's GDB either, at least in the past. (Apple's GDB is inconsistent about "darwin" vs "macosx", not least because it predates the creation of the Darwin project.)
Why do you need both Darwin and Darwin64?  We don't do this for other
operating systems that have both a 32-bit and a 64-bit variant.

This may or may not be necessary - the ABIs are different, and both 32-bit and 64-bit executables can be run at the same time by the same kernel, no rebooting needed. So a GDB session does have to distinguish the two types of executables.
