Neil Roberts 48b8510a06 mingw-cross-compile.sh: Write the build environment to a script
The script now writes out a separate script that can be used to set up
the build environment to $ROOT_DIR/share/env.sh. This can be sourced
in a shell to set up the build environment or it can be given a
command to directly execute in the environment. This makes it easier
to build Clutter from your own source rather than checking it out from
git directly.

# This script will download and setup a cross compilation environment
