Let me be clearer; I think there are some targets we need to allow time
to fix ourselves based on userbase, rather than on maintained-ness.  I
would wager that GDB on Alpha has a fair number of users, and it seems
to work relatively well.  If they prove unreasonably difficult to
multi-arch, well, that's a different story.

Most of SPARC is only multiarch if it snuck in with David's cleanups
recently.  A day-old tree:

tm-sp64.h:#define GDB_MULTI_ARCH GDB_MULTI_ARCH_PARTIAL
tm-sp64linux.h:#define GDB_MULTI_ARCH 0
tm-sun4sol2.h:#define GDB_MULTI_ARCH GDB_MULTI_ARCH_PARTIAL

Someone was working on HP/UX just a little while ago - Jeff Law, I
think.
