Yes, sorry, I meant to say something along these lines in my reply, in
addition to mentioning `sort`, but forgot. Taking a look at this
again, though, makes me wonder if the CHAINLINTTESTS assignment should
be done with `:=` rather than `=` (unless GNU make is smart enough to
only invoke the `wildcard` operation only once, in which case it
wouldn't particularly matter).
