LGTM. I didn't realize that the second and third stages didn't already use a native-only build, although it makes a lot of sense in hindsight.

This did not work as expected. I'm looking into it.

[tstellar]

I see the issue. The 3 stages already build the native target only, but when llvm is built to generate the training data, it enables all the targets.

It turns out we don't need this, closing.
