As far as I can see the only kernel header that gen_facilities.c is actually
interested in is autoconf.h. (autoconf.h will be included via in kconfig.h.)
So it seems the odd $(LINUXINCLUDE) variable in that Makefile could be
replaced with something like:
-include $(srctree)/include/generated/autoconf.h
