In case anyone is interested, I've got the beginnings of a cargo-zigbuild cross-compilation for Pants
https://github.com/pantsbuild/pants/blob/cargo-zig/.github/workflows/release-zigged.yaml
Early days - I was just looking to find some of the compilation quirks (which are all, entirely related to aws-lc-rs). In hindsight, this likely would have been trivial on scie-pants instead, but 🤷
