// A smoke test for the `-l` command line rustc flag, which manually links to the selected
// library. Useful for native libraries, this is roughly equivalent to `#[link]` in Rust code.
// If compilation succeeds, the flag successfully linked the native library.
// See https://github.com/rust-lang/rust/pull/18470

//@ ignore-cross-compile
// Reason: the compiled binary is executed
