A file update in 2018 broke many ports as it misidentified shared
libraries as PIE binaries. r333944 reverted part of the change,
restoring ports builds but misidentifying objects in the opposite
direction.
Earlier this month file 5.39 was imported, and then the change
originally from r333944 was recommitted as r362261. However, the
issue was fixed upstream, so r362261 serves no purpose.

The distinction between ELF header version and OpenPOWER ELF ABI version is
confusing for most of people, so this adds text to "file" output to make it
clear about which OpenPOWER ELF ABI version binary was built for.
The strings used in this change are based on "64-Bit ELF V2 ABI
Specification/3.1. ELF Header" document available at
http://openpowerfoundation.org/wp-content/uploads/resources/leabi/content/dbdoclet.50655241_97607.html
Example:
$ file t1-Flag2 -m -m contrib/file/magic/Magdir/elf t1-Flag2: ELF 64-bit MSB
executable, 64-bit PowerPC or cisco 7500, OpenPOWER ELF V2 ABI, version 1
(FreeBSD), dynamically linked, interpreter /libexec/ld-elf.so.1, for FreeBSD
13.0 (1300033), FreeBSD-style, not stripped

Magic file for dump(8) had this dump and previous dump dates reversed.
Fix order for all three flavours of the dump(8) format.
This fix was committed to upstream repo as magic/Magdir/dump,v 1.17

Merge the latest file(1) in.
Relevent Changelog:
- extend the support for ${x?:} expansions for magic descriptions
- add support for ${x?:} in mime types to handle pie binaries.
- add support for negative offsets (offsets from the end of file)
- close the file on error when writing magic

Magic tests containing "search" or "regex" directives were incorrectly
compiled by "mkmagic" and were effectively ignored. This caused troff
files (for example) to be detected as simply "ASCII text" instead of
as "troff or preprocessor input, ASCII text".

thread specific informations.
In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
- For cores, a new ELF note is added (NT_THRMISC) that can be used for
storing thread specific, miscellaneous, informations. Right now it is
just popluated with a thread name.
GDB, then, retrieves the correct informations from the corefile via the
BFD interface, as it groks the ELF notes and create appropriate
pseudo-sections.
