The problem is still the relative XEN_ROOT specification.
Or the missing .config under XEN_ROOT, so creating this file solves my
problem. :-)

I'd favor the latter, e.g. by adding something like

cfg-create := $(shell touch $(XEN_ROOT)/.config)

to ./Config.mk, or putting the include in a conditional instead
of making use of -include.

As short time measure this seems to be okay.

On the long run I'd prefer to use absolute paths only. Otherwise you've
always a risk to use something from outside the intended build environment.

XEN_ROOT = $(abspath ../..)

seems not too hard to use instead of

XEN_ROOT = ../..

And I'm still favoring usage of conditional setting of XEN_ROOT in included
Makefiles other than config/* to avoid hard to find problems.
