The underlying *object file format* can't handle weak symbols. Any attempt
to use them will ultimately fail.

Looks like they (HP) are using aborted code -- we tried to make SOM
secondary definitions masquerade as weak symbols, but in the end it won't
work due to limitations of secondary definitions. Trust me, if they're
emitting .weak for SOM, it's going to break -- it's just a matter of time.
Of course, the HP provided binaries for GNU tools have always been broken in
various ways -- I strongly recommend against using them.
