Obviously, having slept on it, I should only do the is-it-toybox tests 
when $TEST_HOST is set, and otherwise assume it's toybox for Harold 
Finch reasons. And if there's the occasional false negative on host 
tests with toybox installed via hardlinks: oh well. So we skip some 
tests in that corner case.

I'm going through and adjusting TEST_HOST to pass on Devuan Deadmaus, 
which is a systemd-free fork of Debian Bookworm, I.E. Debian 12, and 
there are SO many brittle...

I try not to expect large chunks of gnu/gnu output to stay stable.
