	bfd/
	* elf32-arm.c (a8_erratum_fix): Add st_type field to record the
	destination mode of the a8 stub.
	(elf32_arm_link_hash_table): Add top_id field.
	(elf32_arm_link_hash_table_create): Initialize top_id.
	(arm_type_of_stub): Update prototype, st_type can now be updated
	by this function. Actual destination address in case of PLT is
	computed here, to help factorizing code.
	(elf32_arm_stub_name): Update prototype, use stub_type additional
	parameter to build stub name.
	(elf32_arm_get_stub_entry): Update prototype, use stub_type
	additional parameter to build stub entry.
	(arm_build_one_stub): Use bfd_put_16/bfd_put_32 instead of
	put_thumb_insn/put_arm_insn as BE8 encoding is now handled later.
	Call elf32_arm_final_link_relocate to process all in-stub
	relocations.
	(elf32_arm_setup_section_lists): Update top_id.
	(cortex_a8_erratum_scan): Record stub destination mode.
	(elf32_arm_size_stubs): Update call to arm_type_of_stub according
	to new prototype.
	(elf32_arm_final_link_relocate): Enable processing of in-stub
	REL32 relocations. Rely on arm_type_of_stub to detect if a stub is
	needed, enabling code factorization.
	(elf32_arm_final_link): Process stub sections.
	(elf32_arm_output_map_sym): Add entry to code/data map.

	ld/testsuite/
	* ld-arm/arm-elf.exp: Change .text start address for
	farcall-thumb-arm tests. Add v4t variant for farcall-mixed-lib
	test.

	* ld-arm/farcall-thumb-arm-blx-pic-veneer.d: Likewise.
	* ld-arm/farcall-thumb-arm.s: Update test. Add a new call to
	potentially generate different types of stubs.
