This, I'm afraid, invalidates what I've said in another reply on
the earlier thread a few minutes ago. What Makefile.kconfig
gets to see must be consistent for FORCE to not be added to
include/config/auto.conf's dependencies by auto.conf.cmd.

Or in other words - did you check (in conjunction with that other
patch fixing incremental rebuilds) whether incremental rebuilds
aren't again becoming full rebuilds because of this when there's
no XEN_CONFIG_EXPERT in the environment?
