I am working on a self-hosted library server for jailbroken kindle and opted for using pure Rust for the KUAL app to sync books and annotations with the server.

It's just running `cargo build --release --target armv7-unknown-linux-musleabihf` with a .cargo/config.toml:

``` [target.armv7-unknown-linux-musleabihf] linker = "rust-lld" rustflags = ["-C", "link-self-contained=yes"]. ```

the downside is I can't use any c-deps. :)
