[committed] Testsuite changes re HP-UX weak support

[John David Anglin]

The change to g++.dg/warn/weak1.C to skip the test on hppa*-*-hpux*
is a known issue with the weak support on this target.  The other
changes fix failures on hppa1.1-hp-hpux10.20.  This target doesn't
have weak symbol support.

Tested on hppa2.0w-hp-hpux11.11, hppa64-hp-hpux11.11 and
hppa1.1-hp-hpux10.20.  Committed to 4.0 and 4.1.
