Cross-platform build (arm64 build from x86_64 host) fails with run_dev.sh

[akupferb]

In previous versions (pre Isaac-ROS 3) of the run_dev.sh script, I could change the PLATFORM arg from being the default "$(uname -m)" to be configured by param for either x86_64 or aarch64 and the build was successful for the full set of layers: {platform}.ros2_humble.realsense.user.isaac... (where the "isaac" layer is our own added Dockerfile)
However, with the new run_dev process which uses the build_image_layers.sh script, when trying to set the PLATFORM to be aarch64 on my x86 host, I get the following error:
