hppa patchset 4 of 4

[Alan Modra <alan at linuxcare dot com dot au>]

ld/ minus emultemp/hppaelf.em because again it's quite a large patch.

ld/ChangeLog
	Changes to create multiple linker stubs, positioned immediately
	before the section where they are required.
	* emultempl/hppaelf.em: Include elf32-hppa.h.
	(stub_sec, file_chain): Delete.
	(hppaelf_create_output_section_statements): Don't make a stub
	section here.
	(hook_stub_info): New struct.
	(hook_in_stub): New function.
	(hppaelf_add_stub_section): New function.
	(hppaelf_finish): Do nothing for relocateable links.  Modify the
	call to elf32_hppa_size_stubs.  Move code for updating section
	layout from here...
	(hppaelf_layaout_sections_again): ..to here, a new function.

	* emultempl/hppaelf.em (hppaelf_delete_padding_statements): Fix
	broken list handling.  Pass in a pointer to the list.
	(hppaelf_finish): Update call to hppaelf_delete_padding_statements
	for above changes.
	(hppaelf_before_parse): Prototype.

	(hppaelf_get_script): Update from elf32.em.
	(ld_hppaelf_emulation): Rename to ld_${EMULATION_NAME}_emulation.
	Change emulation_name field to "${EMULATION_NAME}".  Add
	gld${EMULATION_NAME}_place_orphan. 

	* Makefile.am (ALL_EMULATIONS): Reinstate ehppaelf.o,  add
	ehppalinux.o, sort it.  Regenerate dependencies.
	(ehppalinux.c): Depend on hppaelf.em
	* Makefile.in: Regenerate.
