testcase

>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
  ED_*
  EKERN_*
  EMACH_*
  EMIG_*
it returns NULL.

How to reproduce:
$ gcc -Wall foo.c
$ ./a.out

Seen on Debian GNU/Hurd, with glibc 2.34.
