| bootstrap will detect the host triple as `HOST`, which is set by the `cargo` |
| that's invoking `bootstrap`. `cargo` autodetects `HOST` from the `rustc` it has |
| available (e.g., rust-bootstrap's). The `rustc` from `rust-bootstrap` has |
| `x86_64-unknown-linux-gnu` hardcoded as its host. |
| |
| To break this cycle, hardcode x86_64-pc-linux-gnu here. |
