netbsdpe was deprecated in c2ce831330e10dab4703094491f80b6b9a5c2289.
Since then, a release has passed (2.37), and it was marked obselete in
5c9cbf07f3f972ecffe13d858010b3179df17b32. Unless I am mistaken, that
means we can now remove support altogether.
All branches in the "active" code are remove, and the target is
additionally marked as obsolete next to the other removed ones for
libbfd and gdb.
Per [1] from the NetBSD toolchain list, PE/COFF support was removed a
decade ago. Furthermore, the sole mention of this target in the binutils
commit history was in 2002. Together, I'm led to believe this target
hasn't seen much attention in quite a while.

* Two add subset functions is redundant. Keep the riscv_add_implicit_subset,
and renamed it to riscv_add_subset. Besides, if the subset is added in order,
then we just add it at the tail of the subset list.
* Removed the "-march:" prefix from the error messages. Since not only the
-march= option will use the parser, but also the architecture elf attributes,
the default architecture setting and linker will use the same parser.
* Use a function, riscv_parse_check_conflicts, to check the conflicts
of extensions, including the rv64e and rv32q.
The rv32emc-elf/rv32i-elf/rv32gc-linux/rv64gc-elf/rv64gc-linux regressions
are tested and passed.

If GNU_PROPERTY_1_NEEDED_INDIRECT_EXTERN_ACCESS is set on any input
relocatable files:
1. Don't generate copy relocations.

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.

file descriptor.

The testcase in this PR tickled two bugs fixed here. output_bfd is
NULL when a reloc special_function is called for final linking and
when called from bfd_generic_get_relocated_section_contents. Clearly
using output_bfd is wrong as it results in segfaults. Not only that,
the endianness of the reloc field really should be that of the input.
The second bug was not checking that the entire reloc field was
contained in the section contents.
