That's a one-time issue.  I didn't think it was worth extra hassle to
avoid that.  Do you see any problem with that?  (The "if test" part of
the new target's rules could be updated to check that the
small-ja-dic-option file exists, and generate a non-empty file if
not.)

Yes.  I will figure this out when the next release's pretest will be
prepared.

(We also need to add the file to some *clean targets.)
