bug#66125: 29.1; configure --with-small-ja-dic has no effect

[Ulrich Mueller]

The --with-small-ja-dic configure option of Emacs 29.1 seems to have no
effect.

Actual result:
It will still install the large version of the dictionary, with a size
of almost 5 MB:

$ ls -l /usr/share/emacs/29.1/lisp/leim/ja-dic/
total 9120
-rw-r--r-- 1 ulm users 4798823 Jul 23 10:11 ja-dic.el
-rw-r--r-- 1 ulm users 4535697 Jul 23 10:11 ja-dic.elc

By their date, these are presumably the pre-built files from the
distribution tarball.

Expected result:
A smaller-size Japanese dictionary (about 2.2 MB) should be installed,
as the configure option says.
