[PULL 01/25] configure: allow disable of cross compilation containers

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

Our docker infrastructure isn't quite as multiarch as we would wish so
lets allow the user to disable it if they want. This will allow us to
use still run check-tcg on non-x86 CI setups.
