From Bruno Haible <bruno@clisp.org>:
The function strerrorname_np is supposed to return non-NULL for all defined
errno values.
https://www.gnu.org/software/libc/manual/html_node/Error-Messages.html
On Hurd, for the errnos with names

I guess it's a matter of completing manual/errno.texi with these, help welcome!

test case for Linux/powerpc64le
Similarly, on Linux/powerpc64le: for the errno with name EDEADLOCK
strerrorname_np returns NULL.
How to reproduce:
$ gcc -Wall -O foo-ppc.c
$ ./a.out
strerrorname_np (EDEADLOCK) = (null)
Seen on Linux/ppc64le with glibc 2.35.

mips, powerpc and sparc use a separate value for EDEADLOCK, while all other
architectures alias it to EDEADLK.

Linux missing EDEADLK was already fixed by
3d7d5c10c806ee24f8e35014e41e203002609a3f.

(In reply to Adhemerval Zanella from comment #5)
> Linux missing EDEADLK was already fixed by

Indeed, 3d7d5c10c806ee24f8e35014e41e203002609a3f (most likely) fixed the case
of missing EDEADLOCK on Linux.
So, the only remaining errnos to be added are for Hurd, the errnos with names
ED_*
EKERN_*
EMACH_*
EMIG_*
(as in the original description).
