Rust merged offload support, but we don't build it by default since we're still fighting cmake/bootstrap issues.
In CI, we updated our LLVM submodule a while ago to 22, and along with that, we updated our external clang used to build LLVM to 22.
We've since updated our LLVM submodule to newer patch versions, but kept our external clang unchanged, so now they mismatch and builds fail. I'm able to work around it locally, but prefer not to update our external clang in CI.
We have a gsoc student trying to get Rust-offload to work in CI, so fixing this would unblock them.
