aarch64: Add support for GNU indirect functions.
Add support for STT_GNU_IFUNC symbols to the AArch64 bfd backend. The tests
are ported from the ld-ifunc tests but are enabled for cross builds so can
be run easily without hardware or a simulator.
bfd/ChangeLog:
2013-10-03 Will Newton <will.newton@linaro.org>
* configure: Regenerate.
* configure.in: Build elf-ifunc.o for AArch64.
* elfnn-aarch64.c: Include objalloc.h.
(elfNN_aarch64_local_htab_hash): New function.
(elfNN_aarch64_local_htab_eq): New function.
(elfNN_aarch64_get_local_sym_hash): New function.
(elfNN_aarch64_link_hash_table_create): Initialize local STT_GNU_IFUNC
symbol hash.
(elfNN_aarch64_hash_table_free): Free local STT_GNU_IFUNC symbol hash.
(elfNN_aarch64_final_link_relocate): Add sym argument. Add support
for handling STT_GNU_IFUNC symbols.
(elfNN_aarch64_gc_sweep_hook): Add support for garbage collecting
references to STT_GNU_IFUNC symbols.
(elfNN_aarch64_adjust_dynamic_symbol): Add support for handling
STT_GNU_IFUNC symbols.

(elfNN_aarch64_allocate_local_ifunc_dynrelocs): New function.
(elfNN_aarch64_size_dynamic_sections): Call
elfNN_aarch64_allocate_local_dynrelocs.
(elfNN_aarch64_create_small_pltn_entry): Add info argument.
Add support for creating .iplt entries for STT_GNU_IFUNC symbols.
(elfNN_aarch64_finish_dynamic_symbol): Add support for handling
STT_GNU_IFUNC symbols and .iplt.
(elfNN_aarch64_finish_local_dynamic_symbol): New function.
(elfNN_aarch64_finish_dynamic_sections): Call
elfNN_aarch64_finish_local_dynamic_symbol.
