* 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.

Print a hexadecimal version of any decimal constant that is
outside of the range of -16 to +32.
(print_arm_address): Add a return value of the offset used in the
adress, if it is worth printing a hexadecimal version of it.

destination for defined dynamic symbols when deciding whether to
insert a stub or not.
(allocate_dynrelocs): Make sure functions are not marked as Thumb
when actually accessed through a PLT, even when generating a
shared lib.
