Still not quite sure what the right thing for SKIP_HOST to do is. (It really
indicates "this test isn't portable", although whether it's busybox or debian
failing is more detail than I usually want to record, that's not the intended
purpose of this test suite. It would be _nice_ if there was a general purpose
command line tester, but scope creep...)

I can add test if host is toybox, but [ "$(basename $(readlink -f "$CMDNAME"))"
== toybox ] won't catch standalones, checking $CMDNAME --version output for
"toybox" won't catch sed or false, and you can already test toybox within the
build anyway...

I can make the test attempt anyway and replace FAIL with SKIP in the output, but
if the failure mode is "hangs" or "tries to dirty terabytes of memory until the
OOM killer triggers"....

And thus it's doing what it's doing at the moment, which still seems wrong...

Hmmm... busybox is probably right that it should use the current year.
