PR23207, hppa ld SIGSEGVs on invalid object files

Browse Source 
We don't create PLT call stubs for anything in non-alloc sections,
so it doesn't pay to go looking for them.  The problem is that
non-alloc sections aren't processed by group_sections and thus don't
get a link_sec set up for them.

	PR 23207
	* elf32-hppa.c (final_link_relocate): Don't look for plt call
	stubs in non-alloc sections.
