Which HPPA targets do we still support?

Even ``was'' is being generous here for the hppa*-pro*.  I don't think 
it built on anything other than HP/UX :-(

Personally, I'd just, initally worry about:
	HPPA
	HPPA_64
(and perhaphs HPPA-elf if that is meaningingful?).  I'd expect all the 
others to be broken.
