neodooms/crossbuild repository overview

It seems there aren't recent builds on https://hub.docker.com/r/multiarch/crossbuild⁠ images, though its repo in: https://github.com/multiarch/crossbuild⁠ has been updated (at this time using debian stretch as base). This image uses directly that repo.

The tag jessie is the image as it was the multiarch/crossbuild image in dockerhub at the time of writing this, using Debian Jessie as the base OS.
