// This test tries to check that basic cdylib libraries can be compiled and linked successfully
// with C code, that the cdylib itself can depend on another rlib, and that the library can be built
// with LTO.
//
// - `bar.rs` is a rlib
// - `foo.rs` is a cdylib that relies on an extern crate `bar` and defines two `extern "C"`
// functions:
// - `foo()` which calls `bar::bar()`.
// - `bar()` which implements basic addition.
