* hppa-tdep.c (hppa_lookup_stub_minimal_symbol): New function. 

* hppa-tdep.h (hppa_lookup_stub_minimal_symbol): Add declaration.
        * solib-som.c (som_solib_create_inferior_hook): Replace stub
        msymbol search by call to hppa_lookup_stub_minimal_symbol. This
        extends the search to all objfiles, not just shared libraries.
        Remove unused variable.
