Sigh, I'd actually tried something like this, based on a
stackoverflow.com hint; however, there is so much cruft on that command
line (options with arguments: "-C tests", and in my case: "-j 10"; an
operand that is a target: "check", and an operand that is a macro
definition: "TESTS=...") that (from my bash history) it looks like I
left out the target ("check")...

Thanks!
