bfd/
* elf-bfd.h (struct elf_obj_tdata): Delete dt_soname field. Add
dyn_lib_class field. Rearrange for better packing.
(elf_dt_soname): Delete.
(elf_dyn_lib_class): Define.
* elf.c (bfd_elf_set_dt_needed_name): Update comment.
(bfd_elf_set_dt_needed_soname): Delete.
(bfd_elf_set_dyn_lib_class): New function.
* elflink.h (add_dt_needed_tag): New function. Split out from..

Use elf_dyn_lib_class to set dt_needed and add_needed. Move fallback
initialization of soname.
(elf_link_check_versioned_symbol): Test elf_dyn_lib_class instead of
elf_dt_soname.
