If you had in mind that whenever I do

# config-kernel --set-extraversion /usr/src/linux-build/2.6.4-x2

I would get

# head -5 /usr/src/linux/Makefile
VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 4
EXTRAVERSION = -x2
KBUILD_OUTPUT=$(KBUILD_OUTPUT_PREFIX)/$(MAJOR).$(MINOR).$(PATCHLEVEL)$(EXTRAVERSION)

then I can live with that. I even dare say it would be perfect. Plus, the
output directory would be created by config-kernel, so there is no worry about
it not existing.

Or did you mean something like

# config-kernel /usr/src/linux-build/

to set the prefix, probably only once, and later

# config-kernel --set-extraversion -x2

to set EXTRAVERSION in /usr/src/linux/Makefile every time I switch kernels? The
output directory can still be created by config-kernel at the second step and
users would need to be advized to always use config-kernel and not change
EXTRAVERSION manually. This is not such a big problem though.
