The HP dynamic loader requires all symbols to be defined. I've been
working on a revised method for handling weak undefined symbols introduced
by the crt*.o files. Specifically, they need to be removed from shared
libraries such as libgcc_s.sl. Moving the stubs into their own library
introduced many fails in the gfortran testsuite similar to the following:
