* 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-mixed-lib-v4t.d: New test.
* ld-arm/farcall-mixed-lib1.s: Don't force armv5t.
* ld-arm/farcall-mixed-lib2.s: Likewise.
* ld-arm/arm-call.d: Update expected results.

* 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.
