This is not a real dockfile change. You can decide whether to take it, unless it's possible that d/s infra may use arm machines someday

I like the idea, though I think it would be even better if we could specify a target architecture with GOARCH like I had done here for NTO: openshift/cluster-node-tuning-operator#1135

Building arm images is beyond the scope of this PR. I am happy to make that change if I can verify the output. Does NTO get CI running on arm hardware now?

I'm not sure what architecture the CI runs on but the change was very useful for testing since by using GOARCH you can build any arch from any arch (within the supported golang limits)
