Will Newton 593f8f2938 bfd/elf64-aarch64.c: Remove dead code. 
The relocs_copied member is never assigned a non-NULL value, so
this code does not appear to be used.

bfd/ChangeLog:

2013-05-20  Will Newton  <will.newton@linaro.org>

	* elf64-aarch64.c (elf64_aarch64_link_hash_entry): Remove
	relocs_copied member.
	(elf64_aarch64_link_hash_newfunc): Remove initialization of
	relocs_copied member.
	(elf64_aarch64_copy_indirect_symbol): Remove code to copy
	relocs_copied member.
