readelf: document that -u / --unwind is not yet implemented

ELF tool chain readelf accepts -u / --unwind but just ignores the
option. This was previously undocumented, which could be confusing for
someone encountering `readelf -u` (in a script or GNU readelf example).

Update to ELF Tool Chain r3668

Highlights:
- Make sure that only TLS sections are sorted into TLS segment.
- Fixed multiple errors in "Section to Segment mapping".
- Man page updates
- ar improvements
- elfcopy: avoid filter_reloc uninitialized variable for rela
- elfcopy: avoid stripping relocations from static binaries
- readelf: avoid printing directory in front of absolute path
- readelf: add NT_FREEBSD_FEATURE_CTL FreeBSD note type
- test improvements

NOTES:

Some of these changes originated in FreeBSD and simply reduce diffs
between contrib and vendor.

ELF Tool Chain ar is not (currently) used in FreeBSD, and there are
improvements in both FreeBSD and ELF Tool Chain ar that are not in
the other.

- 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.
