lto: Don't include unused LTO archive members in output

When plugin_object_p is called by elf_link_is_defined_archive_symbol to
check if a symbol in archive is a real definition, set archive member
plugin_format to bfd_plugin_yes_unused to avoid including the unused LTO
archive members in linker output.  When plugin_object_p is called as
known used, call plugin claim_file if plugin_format is bfd_plugin_unknown
or bfd_plugin_yes_unused.

To get the proper support for archives with LTO common symbols with GCC,
the GCC fix for

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116361

is needed.

* archures.c (bfd_arch_get_compatible): Treat bfd_plugin_yes_unused
the same as bfd_plugin_yes.
* elflink.c (elf_link_is_defined_archive_symbol): Likewise.

* plugin.c (plugin_call_claim_file): Add an argument to return
if LDPT_REGISTER_CLAIM_FILE_HOOK_V2 is used.
(plugin_object_p): When KNOWN_USED is false, we call plugin
claim_file if plugin_format is bfd_plugin_unknown and set
plugin_format to bfd_plugin_yes_unused on LTO object.  When
KNOWN_USED is true, we call plugin claim_file if plugin_format
is bfd_plugin_unknown or bfd_plugin_yes_unused.

I see the same problem with gcc/12.3.0 and gcc/13.2.0.

I am running on ufront.cs.rice.edu
OSNAME: Linux RHEL_(Ootpa) (4.18.0-477.64.1.el8_8.x86_64)
NCPUs: 96
CPUTYPE: AMD EPYC 7402 24-Core Processor AMD EPYC 7402 24-Core Processor

Question: how can I get the sources of gprofng?

Thanks,
Marty
