Ah, above was just a sample only intended for LE build.

I know that, but $(obj)include/autoconf.mk will be included by
$(TOPDIR)/config.mk.  Then what a rationale for including it redundantly
by $(TOPDIR/Makefile?  I assume that Wolfgang is probably requesting the
explanation for that.

Autoconf.mk is expected to be generated *before* $(TOPDIR)/config.mk is
included, right?  If so, do you think your patch is a reasonable enough?
Or do we need to consider another approach?
