Are these binaries no longer needed?

Image size reduction for reference btw:

<none>                        before       859aa85ac35e   41 seconds ago   1.28GB
<none>                        after        524b016d2b88   2 minutes ago    94.2MB

Thanks for this. For now, our customer needs a slim image, when the request comes for an image with all the toolchain included we'd consider it differently.
