+       * elf-bfd.h (struct elf_link_hash_table): Rename "loaded" to
+       "dyn_loaded".
+       (bfd_elf_add_dt_needed_tag): Declare.
+       * elf-strtab.c (_bfd_elf_strtab_restore): Handle NULL buf.
+       * elflink.c (bfd_elf_add_dt_needed_tag): Make global and rename
+       from elf_add_dt_needed_tag.  Remove soname and doit param.
+       (elf_link_add_object_symbols): Don't use elf_add_dt_needed_tag
+       to see whether as-needed lib is already loaded, use dyn_loaded
+       list instead.  When saving and restoring around as-needed lib
+       handle possibility that dynstr has not been initialised.  Don't
+       add DT_NEEDED tags here.  Limit dyn_loaded list to dynamic libs.
+       Mark libs loaded via DT_NEEDED entries of other libs with
+       DYN_NO_NEEDED if they should not be mentioned in DT_NEEDED of
+       the output.
+       (elf_link_check_versioned_symbol): Remove now unneccesary
+       DYNAMIC check when traversing dyn_loaded list.

        * bfdio.c (bfd_get_file_size): Ignore bogus archive element sizes.
