currently we don't build any cross compilers on s390x. Is this a scenario
which is needed?
We do that on ppc64el, given that you actually can buy even some workstations.
and if needed, which targets should be supported?

Title:
debian/rules editconfigs does not work on s390x to change s390x only
configs
Status in Ubuntu on IBM z Systems:
Incomplete
Status in linux-5.4 package in Ubuntu:

On s390x

cd linux-*
fakeroot ./debian/rules clean
./debian/rules editconfig

/bin/bash -e debian/scripts/misc/kernelconfig editconfigs
Do you want to edit config: amd64/config.flavour.generic? [Y/n] n

And indeed i do not have x86_64-linux-gnu-gcc crosscompiler available
to build on s390x for amd64, and also I don't want to touch amd64
configs. Only s390x ones.
As a user, I should be able to rebuild ports architecture kernel with
tweaked config for testing, self-hosted without cross-compilers.
