[Qemu-devel] [RFC/POC PATCH 2/4] new tests/docker/dockerfiles/debian-multiarch-cross.docker

["Alex Bennée" <alex.bennee@linaro.org>]

This provides a basic Debian install with access to the emdebian cross
compilers for armhf, arm64 and ppc64el. On its own it provides the
basic cross build essentials for building any of those architectures.
More complex cross-compilations would need to install library
dependencies on top of this image.

An example use:

  docker run --rm -it \
    -v /home/alex/lsrc/qemu/qemu.git/:/home/alex/lsrc/qemu/qemu.git/ \
    --user=alex:alex \
    -w /home/alex/lsrc/qemu/qemu.git/arm-linux-user/tests \
    -e CROSS_CC="arm-linux-gnueabihf-gcc" \
    debian:cross make -f ../../tests/tcg/arm/Makefile
