section in the SOM file.
* (find_return_regnum): New routine. Uses find_unwind_entry() to
figure out where the caller's return address is stored.

ensures that the given name is unique, and will generate a unique
one if necessary.

* (make_bfd_asection): Call bfd_make_section to do the dirty
work. Simplify code somewhat.
* (hppa_core_file_p): Use proper name for stack section.
