bfd/
PR ld/11304
* elf.c (_bfd_elf_init_private_section_data): Rename need_group
to final_link and invert. For final link allow some flags to
differ. Don't specially allow flags to be all zero.
ld/
* ldlang.c (init_os): Remove isec param. Don't check for
bfd_section already set or call bfd_init_private_section_data
here.
(exp_init_os): Update init_os call.
(lang_add_section): Tidy. Really don't set SEC_LINK_ONCE
flags. Call bfd_init_private_section_data here.
(map_input_to_output_sections): Tidy. Update init_os calls.
Use os->sectype to select sec flags for lang_data_statement.
