The symbol is deprecated by strerror since its usage imposes some issues
such as copy relocations.

Its internal name is also changed to _sys_errlist_internal to avoid
static linking usage.  The compat code is also refactored by removing
the over enginered errlist-compat.c generation from manual entried and
extra comment token in linker script file.  It disantangle the code
generation from manual and simplify both Linux and Hurd compat code.

The definitions from errlist.c are moved to errlist.h and a new test
is added to avoid a new errno entry without an associated one in manual.

Checked on x86_64-linux-gnu and i686-linux-gnu. I also run a check-abi
on all affected platforms.

Agreed, thanks for deprecating this.

OK for master if you copy all TRANS statements into C-style comments
in the final committed version of errlist.h, these are special comments
processed by po/Makefile instructions to gettext.

I verified that libc.pot regeneration catches all the translations
in errlist.h (but the translation helper text in TRANS is missing as
noted).

Tested on x86_64 and i686.

OK. Thanks for that.

Likewise see my note about updating packaging change notes in the wiki for
the release such that we have a summary for downstream maintainers that may
need to fix distro software. While they might read the NEWS it's easier to
point them at a detailed list of packaging changes that we write (and the
audience for those is downstream distro maintainers rather than the more
generic NEWS information).
