Update the kernel package to allow building for multiple architectures with a single set of sources. Changes: - Add kernel configs for all architectures - Detect at runtime the correct target architecture and kernel compressed image location. This is done with the script kata-multiarch.sh Note that debian control files still need to be updated to handle Multi-Arch, so that they are not tied to the architecture on which `linux-container/update.sh` is run. Fixes: #262 Signed-off-by: Marco Vedovati <mvedovati@suse.com>
