This fixes build failures on older releases that lack various
definitions such as EM_AARCH64 (which was unfixed before this).
Revert all of the recent compatibility changes that worked around this
problem.
This uses the same method of using the in-tree header as lib/libelf,
lib/libdwarf and usr.bin/readelf.

This fixes a EFI/PE header issue that prevented elfcopy-produced .efi
files from working with Secure Boot:
Make sure section raw size is always padded to multiple of
FileAlignment from the optional header, as requested by the PE
specification. This change should reduce the diff between PE image
generated by Binutils objcopy and elftoolchain elfcopy.

Improvements include:
* Add support for reporting and handling a number of new constants in
various tools, including:
* CloudABI OSABI
* DT_TLSDESC_*
* i386, MIPS, SPARC and amd64 relocations
* C++ demangler bug fixes
* Man page updates
* Improved input validation in several tools
This update also reduces diffs against upstream as a number of fixes
included in upstream were previously cherry-picked into FreeBSD.

It's provided by sys.mk so there's no need to derive it from ${.CURDIR}.

Some notable improvements include:
readelf:
- Add AArch64 relocation definitions.
- Report value of unknown relocation types.
elfcopy:
- Consider symbols with STB_GNU_UNIQUE binding as global symbols.
- Fixed support for VMA adjustment for loadable sections found
in relocatable objects.
- Handle nameless global symbols.
- Improve wildcard matching for !-prefixed symbols.
- Add PE/COFF support.
elfdump:
- Improve section type reporting.
- Add MIPS-specific section types.
This update also includes a significant number of bug fixes.

Highlights (upstream revisions):
- Fix SHT_GROUP handling in elfcopy/strip (3206 3220 3221)
- Misc elfcopy / strip bug fixes (3215 3216 3217)
- Many C++ demangler improvements (3199 3200 3201 3202 3203 3204 3205
3208 3210 3211 3212)
- Improve GNU binutils compatibility in elfcopy / strip (3213 3214)
- Add -g option to readelf(1): dump contents of section groups (3219)
- Add EM_IAMCU 32-bit Intel MCU (3198)
Also add a compat #define for building with older FreeBSD ELF headers.
The GRP_COMDAT flag was added to elf_common.h in r283110, but it's not
available during the bootstrap build. It is also convenient to be able
to build on older hosts.
Thanks to antoine@ for tracking down issues through multiple exp-runs
and to kaiw@ for fixing.

The last elftoolchain update is upstream rev 3136. Update our reported
version and add M (Modified) suffix as our elftoolchain contains
additional fixes not yet committed upstream.

This includes a number of libdwarf improvements (particularly DWARF4
related) and updates to elftoolchain tools such as strip(1). It also
includes a large number of miscellaneous fixes (memory leaks, sign and
cast warnings, integer overflow and underflow, etc.).
This is a merge of r276167,276170-276172 from the
projects/elftoolchain-update-r3130 branch.
