"As long as it available", but is it?  I thought the Debian kernels are
built without CONFIG_IKCONFIG_PROC because that wastes some memory and
the config is always available from /boot/config-$(uname-r).

And has the additional benefit that you learn a lot the hard way by
building kernels that fail to boot or lack important features.  In this
case, however, it is best not to bother with make-kpkg at all; the
"make && make install && make modules_install" triplet will save a lot
of time on subsequent compilations.
