cross-compilation

[Gankra]

This will be the hardest nut to crack, and basically a fantasy in my mind, but ideally you would be able to:

• cross-compile for a different platform (hard)
• deploy the tests to that platform (hellish)
• remote the results back (hard)

One possible way to do this would be to basically take the deployment/remoting out of our own hands and require the user to figure out by just emitting binaries and some kind of manifest file. Then the user is responsible for deploying+running the binaries, which will attempt to write to some file. Then the file can be brought back to native world and fed into us for final reporting (if that output file isn't good enough).

You could use qemu user mode emulation on linux to run binaries for another architecture for as long as it is still a linux executable.

I would love for this to be possible as we've run into so many ABI mismatches between the Xtensa ports of GCC and LLVM/Rust, and it would be really cool to be able to automatically validate them against each other. Unfortunately building Linux binaries for it is a right hassle right now with GCC, and I think not really possible yet with LLVM/Clang, so being able to run the binaries manually on-device somehow would be useful here.
