Delete Tru64 support

This commit does most of the mechanical removal.  IOW, the easy part.

procfs.c isn't touched beyond removing a couple obvious bits that are
guarded by a couple macros defined in config/alpha/nm-osf3.h.  Going
beyond that for procfs.c & co would be a harder excision that
potentially affects Solaris.

Some comments in the generic alpha code ABIs that may still be
relevant and I wouldn't know what to do with them.  That can always be
done on a separate pass, preferably by someone who can test on alpha.

A couple other spots have references to OSF/Tru64 and related files
being removed, but it felt like removing them would make things worse,
not better.  We can revisit those when we next need to touch that
code.

I didn't remove a reference to osf in testsuite/lib/future.exp, as I
believe that code is imported from DejaGNU.

Built and tested on x86_64 Fedora 20, with --enable-targets=all.

Tested that building for --target=alpha-osf3 on x86_64 Fedora 20
fails with:

 checking for default auto-load directory... $debugdir:$datadir/auto-load
 checking for default auto-load safe-path... $debugdir:$datadir/auto-load
 *** Configuration alpha-unknown-osf3 is obsolete.
 *** Support has been REMOVED.
 make[1]: *** [configure-gdb] Error 1
 make[1]: Leaving directory `build-osf'
 make: *** [all] Error 2
