ae500c1ff8 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.

94bb24b387 Use the in-tree sys/elf_common.h to build libelftc.
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.

d38447b51d Update to ELF Tool Chain r3477
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.

b6b6f9cc7c Update to ELF Tool Chain r3475
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.

2821bdccaa elftoolchain: Use ${SRCTOP} for the top of the FreeBSD tree

3ef90571c1 Update to ELF Tool Chain r3223
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.
