Does not look like it's listed in the list of files that objects depend
on?
I am not sure what is LIB_H since it's not defined anywhere.

There are various autodep tools to generate real dependencies, but I
suspect you can just specify *.h so any header file rebuilds
everything?

smatch.o: smatch.c $(LIB_H) smatch.h check_list.h check_list_local.h
        $(CC) $(CFLAGS) -c smatch.c -
DSMATCHDATADIR=3D'"$(smatch_datadir)"'

$(SMATCH_OBJS) $(SMATCH_CHECKS): smatch.h smatch_slist.h smatch_extra.h
\
        smatch_constants.h avl.h
