provide CUDA builds for linux on arm64

[sebffischer]

Following up on #42, is it also possible to provide CUDA builds here?

Sadly, the ruleset provided by Google that XLA uses doesn't support CUDA cross-compilation. We do have a project that enables it internally but porting it to xla wouldn't make sense for us at this stage.

Thanks! Can you explain in a bit in more detail what you mean by that?
