Will Newton June 3, 2013, 8:23 a.m.
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.

Changes since RFC:
 - Relocation number allocated by ARM
 - Fix testsuite failures on aarch64_be-elf and aarch64-elf.

bfd/ChangeLog:

one that you intend to use?
