Cross compiling RISC V with spike emulation

@nizarzaza interesting. we do have a very peculiar way we build TFLite. iiuc it’s due to an API problem. as far as i know folks have been successful using TFLite installed from PyPI though, so I’m not sure if this is needed for particular models or what.

I don’t have cycles to investigate this specifically right now, but I am working on [RFC] Python Dependencies in TVM CI Containers at the moment and as part of that I’ll try to use PyPI-installed TFLite in the CI. I can update this thread as I learn more with that.
