7dc45d65e3 readelf(1) -S: Include zero index and match binutils' no-name
Include the SHN_UNDEF (zero) index special section in extended-attribute
ELF files, like GNU binutils' readelf.

Additionally, print "<no-name>" for sections without names, like GNU
binutils.

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.

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.

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.
