For cross-compiling scenarios it's often necessary to pass CMAKE_TOOLCHAIN_FILE to cmake. In a large project like Servo there might be a lot of cmake-using dependencies that will all need to pass it, so pulling this from an environment variable will let people doing cross-compiles specify this just once.
