A patch has been posted at
http://gcc.gnu.org/ml/gcc-patches/2012-09/msg01602.html and I have also tested
it on x86_64-apple-darwin10. Note that it won't fix the failure for 32-bit
hppa*-*-hpux*.
The fix used also works for gcc.dg/attr-weakref-1.c

For the record, following the suggestions of Richard Guenther and Tobias Burnus
on IRC, I have tested the attached patch which mimics gcc.dg/attr-weakref-1.c
and also works on x86_64-apple-darwin10 and powerpc-apple-darwin9.
