PR22537, Segmentation fault with static PIE
The only stub type that makes sense for undefined symbols, or those
defined in shared libraries, is a plt call stub. This patch arranges
to have "destination" set to -1 on such symbols, making for an easy
test in hppa_type_of_stub.
PR 22537
* elf32-hppa.c (elf32_hppa_size_stubs): Init "destination" to -1.
(hppa_type_of_stub): Don't return a long branch stub for
symbols other than those defined statically.
