I did some tests and ended up replacing the small-ja-dic-option recipe
in leim/Makefile.in with something very simple:

# This is used to support regeneration of ja-dic when the SMALL_JA_DIC
# option is flipped by the configure-time option.
small-ja-dic-option: ../config.status
	$(AM_V_GEN)echo "small ja-dic option: $(SMALL_JA_DIC)" > $@.$$$$ && \
	${top_srcdir}/build-aux/move-if-change $@.$$$$ $@

AFAICS this does what is intended, i.e. the detour via recording the
option in ja-dic.el isn't even needed.
