4 unexpected results:
FAILED process-tests/fd-setsize-no-crash/make-network-process
FAILED process-tests/fd-setsize-no-crash/make-pipe-process
FAILED process-tests/fd-setsize-no-crash/make-process
FAILED process-tests/fd-setsize-no-crash/make-serial-process
This fails on systems without the "errno" executable.

This breaks several tests on emba.gnu.org, see for example
<https://emba.gnu.org/emacs/emacs/-/jobs/9668/raw>.
