emacs-29 7d5fee0feaa: Support regeneration of ja-dic.el under '--with-small-ja-dic'

[Eli Zaretskii]

branch: emacs-29
commit 7d5fee0feaa5740f3fbbfc6d5f13855bf58b9c25
Author: Eli Zaretskii <eliz@gnu.org>
Commit: Eli Zaretskii <eliz@gnu.org>

    Support regeneration of ja-dic.el under '--with-small-ja-dic'
    
    * lisp/international/ja-dic-cnv.el (skkdic-convert): Record the
    value of SMALL_JA_DIC option used to produce ja-dic.el.
    * leim/Makefile.in (small-ja-dic-option): New target, triggers
    regeneration of ja-dic.el when the value of SMALL_JA_DIC option
    changes by the configure script.  Suggested by Ulrich Mueller
    <ulm@gentoo.org>.
    (${leimdir}/ja-dic/ja-dic.el): Depend on 'small-ja-dic-option'.
    (Bug#66125)
    
    * make-dist (possibly_non_vc_files):
    * .gitignore: Add 'leim/small-ja-dic-option'.
