Will Newton 1419bbe571 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_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

	(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.
