2011-01-13  H.J. Lu  <hongjiu.lu@intel.com>

	* elf64-x86-64.c (elf_x86_64_link_hash_table): Remove
	swap_reloca_out.
	(elf_x86_64_link_hash_table_create): Don't set swap_reloca_out.
	(elf_x86_64_check_relocs): Align relocation section to 4 byte
	for 32bit.
	(elf_x86_64_gc_sweep_hook): Replace ELF64_ST_TYPE with
	ELF_ST_TYPE.
	(elf_x86_64_finish_dynamic_symbol): Updated.
	(elf_x86_64_finish_dynamic_sections): Don't use
	Elf64_External_Dyn, bfd_elf64_swap_dyn_in, nor
	bfd_elf64_swap_dyn_out.
