Hey Miguel,

Are you saying you'd prefer that we pick this up on the x86 side? I'm
totally happy to do that, and it's obviously patching x86-specific
sections of the rust scripts.

If I'm understanding the ask.... Just curious though, what makes that
preferable? It's in a rust-specific file
(scripts/generate_rust_target.rs) and I'd guess that it'd be easier to
take it through the rust tree since it's more likely to collide with
stuff there and also be closer to the folks that can competently resolve
any merge problems.
