	* elf32-ppc.c (ppc_elf_plt_type): New enumeration.
	(ppc_elf_link_hash_table): Replace old_got and new_got with
	plt_type and can_use_new_plt.
	(ppc_elf_create_dynamic_sections): Add SEC_HAS_CONTENTS,
	SEC_LOAD and SEC_READONLY to the VxWorks .plt flags.
	(ppc_elf_check_relocs): Set can_use_new_plt instead of new_plt.
	Move from plt_type == PLT_UNSET to PLT_OLD instead of setting old_plt.
	(ppc_elf_select_plt_layout): Move from plt_type == PLT_UNSET to
	either plt_type == PLT_OLD or plt_type == PLT_NEW.  Assert that
	this function should not be called for VxWorks targets.
	(ppc_elf_tls_setup): Use plt_type instead of old_got.
	(allocate_got): Likewise.  Rearrange so that max_before_header
	is only used for PLT_OLD and PLT_NEW.
	(allocate_dynrelocs): Use plt_type instead of old_got and is_vxworks.
	(ppc_elf_size_dynamic_sections): Likewise.
	(ppc_elf_relax_section): Likewise.
	(ppc_elf_relocate_section): Likewise.
	(ppc_elf_finish_dynamic_symbol): Likewise.
	(ppc_elf_vxworks_link_hash_table_create): Initialize plt_type.

ld/

	* emulparams/elf32ppc.sh: ...here.
	* emulparams/elf32ppcvxworks.sh: Include elf32ppccommon.sh
	instead of elf32ppc.sh.
	(BSS_PLT): Remove override.
	* Makefile.am (eelf32lppc.c): Depend on elf32ppccommons.h.
