Perhaps we could try to improve things a little bit so that it works
better out of the box ?

If some kernel options are really absolutely needed for Docker to work,
then maybe we should make sure they are enabled: linux/linux.mk already
does that for a few packages.

Alternatively (or additionally), we can add a
package/docker-engine/docker-engine.txt file that gives some
details/suggestions on how to setup Docker in Buildroot.
