tests/run-make/dynamic-loading-cdylib/rmake.rs

// Checks that dynamically loading and unloading cdylib libraries works,
// both for simple functions and for functions that rely on the Rust runtime
// (that use thread local storage with destructors).
//
// - `foo.rs` is a cdylib.
// - `load_and_unload.rs` is a binary that loads and unloads the cdylib.

//@ ignore-cross-compile
