Log message:
    PR ld/12365
    include/
    * bfdlink.h (struct bfd_link_callbacks): Modify multiple_definition
    and multiple_common parameters to pass in a bfd_link_hash_entry
    pointer rather than name,bfd etc. found in the hash entry.
    bfd/
    * elflink.c (_bfd_elf_merge_symbol): Update multiple_common calls.
    * linker.c (_bfd_generic_link_add_one_symbol): Likewise.  Call
    multiple_definition regardless of allow_multiple_definition.
    * simple.c (simple_dummy_multiple_definition): Update.
    * xcofflink.c (xcoff_link_add_symbols): Update multiple_definition
    calls.
    ld/
    * ldmain.c (multiple_definition): Take a bfd_link_hash_entry
    pointer arg rather than "name", "obfd", "osec", "oval".  Add code
    removed from linker.c.  Hack around xcofflink.c oddity in
    passing NULL nbfd.
    (multiple_common): Similarly.
    * plugin.c (orig_allow_multiple_defs): Delete.
    (plugin_call_all_symbols_read): Don't twiddle allow_multiple_definition.
    (plugin_multiple_definition): Update.
