This is out of scope, but I'd love to use Rust on the Raspberry Pi, too, so let's merge it. :-)

To target ARM hard float (Raspberry Pi):
```sh
rust-musl-builder cargo build --target=armv7-unknown-linux-gnueabihf --release
```
This command assumes that `$(pwd)` is readable and writable by uid 1000, gid 1000. It will output binaries in `target/x86_64-unknown-linux-musl/release`. At the moment, it doesn't attempt to cache libraries between builds, so this is best reserved for making final release builds.
