* 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.
