bug#52322: `make --question info` always fails

[Stefan Kangas]

This command on emacs-28 and master always fails:

    make --question info

Here is a reproducer:

    make info && make --question info || echo "failed"

This breaks the `make-dist` script, where we rely on `make --question
info' returning 0 to continue.  I had to comment out that line to
produce the first pretest.

I have bisected this error to the following commit:
