* elflink.h (elf_fix_symbol_flags): Copy flags to weakdef using

elf_backend_copy_indirect_symbol so that backend has a chance to
	copy other necessary fields.
	* elf-bfd.h (struct elf_backend_data): Update description of
	elf_backend_copy_indirect_symbol.
	* elf.c (_bfd_elf_link_hash_copy_indirect): Bail out after
	copying flags if this is a weakdef.
	* elfxx-ia64.c (elfNN_ia64_hash_copy_indirect): Likewise.
	(elfNN_ia64_aix_add_symbol_hook): Use elf_link_hash_lookup rather
	than bfd_link_hash_lookup.
	* elf32-i386 (elf_i386_adjust_dynamic_symbol): Don't do copy
	reloc processing for weakdefs.
	* elf32-hppa.c (elf32_hppa_adjust_dynamic_symbol): Likewise.
	* elf64-ppc.c (ppc64_elf_adjust_dynamic_symbol): Likewise.
