5.1 Release criteria (with patch)

[Michael Elizabeth Chastain]

native hppa1.1-hp-hpux10.20 does not build.  See PR gdb/63:

  http://sources.redhat.com/cgi-bin/gnatsweb.pl?cmd=view&databse=gdb&pr=63
  "build failure, native hppa1.1-hp-hpux10.20, no_shared_libraries"

native hppa2.0w-hp-hpux11.00 probably also has this problem.  Right now
it has an ltconfig problem standing in front so I can't see.

I don't know if "hpux gdb builds" merits a place in TODO or not,
that's the release manager's decision.
