new: debian docker targets for cross-compiling

This provides a basic Debian install with access to the emdebian cross
compilers. The debian-armhf-cross and debian-arm64-cross targets build
on the basic Debian image to allow cross compiling to those targets.

A new environment variable (QEMU_CONFIGURE_OPTS) is set as part of the
docker container and passed to the build to specify the
--cross-prefix. The user still calls the build in the usual way, for
example:

  make docker-test-build@debian-arm64-cross \
    TARGET_LIST="aarch64-softmmu,aarch64-linux-user"
