Ah, so it's right there in black and white, plain as day! Further
evidence I need to be culled from the herd. Thanks (of course).

On a tenuously related note, for some reason, I'm unable to run

  make -C test -j<NN> check-lisp-erc ...

without incurring a "'warning: jobserver unavailable: using -j1". Plain
old -j without the <NN> works fine, and other targets I've tried, like
check and check-expensive, seem unaffected.

(Apologies if this is nonsense or old news or should be discussed
elsewhere: a cursory search on the bug tracker and the help list came up
empty, and the few hits on emacs-devel for "jobserver unavailable" were
all build-related red herrings, like [1].)

FWIW, the course of action prescribed by the info node "(make) Error
Messages", namely, prepending a "+", seems to remedy the problem.

  diff --git a/test/Makefile.in b/test/Makefile.in
  index 3b6e116e65..c0256d770d 100644

Sorry if that's just noise. As you're well aware, I know nothing! Thanks
again.
