The question is, whether we can change .y.c rule in sys.mk to make 
it -jN
(as pointed out by Brad).
We can't if YFLAGS include -d. Because our yacc has a slightly 
surprising
meaning of the -o option. It does set the name of the c-file and ALSO 
alters
the prefix for the headre file.
Ah.. yuck. What about this, then?

-# XXX not -j safe
+# XXX hopefully -j safe..
.y.c:
-	${YACC} ${YFLAGS} ${.IMPSRC}
-	mv y.tab.c ${.TARGET}
+	${YACC} ${YFLAGS} -b $$$$ ${.IMPSRC}
+	mv $$$$.tab.c ${.TARGET}
+.if !empty(${YFLAGS:M-d})
+	mv $$$$.tab.h y.tab.h
+.endif
This is really evil. Don't we want to just kick this questionable 
"portability"? We already broke much more legacy things...
