A couple tests were using `BOOTSTRAP_CARGO` with `-Zbuild-std`, but that stage0 cargo might not always be in sync with in-tree changes. In particular, those tests started failing on the beta branch because the older cargo couldn't find the library `Cargo.lock`, and then couldn't build the latest version of `compiler_builtins` that had nightly changes.

//! Test building of the `cortex-m` crate, a foundational crate in the embedded ecosystem

//! for a collection of thumb targets. This is a smoke test that verifies that both cargo

|
|
//! How to run this
|
|
//! $ ./x.py clean
|
|
//! $ ./x.py test --target thumbv6m-none-eabi,thumbv7m-none-eabi tests/run-make
