elf/riscv: Fix relaxation with aliases [PR28021]

the fix for PR22756 only changed behaviour for hidden aliases,
but the same situation exists for non-hidden aliases: sym_hashes[]
can contain multiple entries pointing to the same symbol structure
leading to relaxation adjustment to be applied twice.

Fix this by testing for duplicates for everything that looks like it
has a version.

ld: Check archive only for archive member

This is a known issue already partially fixed in binutils/sysdep.h. For
gprof, the same fix needs to be applied in bfd/sysdep.h, as the
following patch does. Tested on i386-pc-solaris2.10 and
i386-pc-solaris2.11.

and in a couple of other places. The platform lacks strnlen, and while
libiberty.h can provide a fallback declaration, the necessary configure
test isn't run.

Fixed with the following patch. Tested on i386-pc-solaris2.10.

ld: Cache and reuse the IR archive file descriptor

Linker plugin_object_p opens the IR archive for each IR archive member.
For GCC plugin, plugin_object_p closes the archive file descriptor. But
for LLVM plugin, the archive file descriptor remains open. If there are
3000 IR archive members, there are 3000 file descriptors for them. We
can run out of file descriptors petty easily.

1. Add archive_plugin_fd and archive_plugin_fd_open_count to bfd so that
we can cache and reuse the IR archive file descriptor for all IR archive
members in the archive.
2. Add bfd_plugin_close_file_descriptor to properly close the IR archive
file descriptor.
