This is required in order to build on non-FreeBSD systems without setting
all the XAR/XSTRINGS/etc. variables

r349482 introduced the definitions and descriptions of the RISC-V
specific e_flags values to elftoolchain. However, the description for
the EF_RISCV_RVE flag was incorrectly duplicated from EF_RISCV_RVC. Fix
this by providing the proper description for this flag.

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.

Improvements include:
* readelf: report all relocation types in rel/rela for MIPS N64
* readelf: add ELFOSABI_ARM_AEABI
* elfdump: add ELFOSABI_ARM_AEABI and ELFOSABI_ARM
* Add recent RISC-V relocations
* elfcopy: use elftc_timestamp, to support SOURCE_DATE_EPOCH
Sponsored by: The FreeBSD Foundation
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.

- 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 (not already in the FreeBSD tree):
- addr2line: Speed up and support searching inlined functions
- addr2line: Support -i, -a, -p options
- readelf: Add some ARM relocation types
- readelf, libelf: Avoid reading beyond end of buffer/file

Highlights (not already in the FreeBSD tree):
- addr2line: Fixed multiple memory leaks related to DIE allocation
- readelf: improve sh_link validation
- various man page improvements

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.
