This image does not need to be run manually. Instead, there is a helper
script to execute build commands on source code existing on the local
host filesystem. This script is bundled with the image.

The dockcross script will execute the given command-line inside the
container, along with all arguments passed after the command. Commands
that evaluate environmental variables in the image, like
**$CC** or **$CXX** above, should be executed in [bash -c].
The present working directory is mounted within the image, which can be
used to make source code available in the Docker container.
