bfd/
* elflink.c (elf_link_add_object_symbols): Don't create link dynamic
sections immediately when linking shared libs. Instead, wait until
we know a lib is needed.
(_bfd_elf_link_create_dynstrtab): Extract from..
(_bfd_elf_link_create_dynamic_sections_): ..here.
(elf_add_dt_needed_tag): Call _bfd_elf_link_create_dynstrtab and
_bfd_elf_link_create_dynamic_sections. Add abfd param. Allow
for non-existent .dynamic.
(elf_link_output_extsym): Don't complain about undefined symbols
in as-needed dynamic libs that aren't actually linked.
ld/
* emultempl/elf32.em (gld${EMULATION_NAME}_try_needed): Formatting.
(gld${EMULATION_NAME}_after_open): Ignore needed libs if they were
only needed by an as-needed lib that didn't get linked.
