Thank you for this patch. Unfortunately, it does not work as intended
because the call to test_have_prereq in test_skip does not split
the prereq tokens so that tests with space-separated prerequisite tokens
are always skipped.

My first attempt to solve that is to remove the quotes from the
test_have_prereq call in test_skip; but I think that this simple
solution is rather unintuitive, and will look like a bug if you inspect
the code again in two months.

You could squash in the patch below, where I chose to concatenate
tokens with '+' because I dislike the extra quoting that is otherwise
necessary at the call site. The downside is that it plays games with
IFS, which you might find too ugly and not worth it. It's your call.

BTW, I didn't dare test this as root on my production system; I'll do
that later today elsewhere.
