// If a dylib is being produced, the compiler will first check to see if it can
// be created entirely statically before falling back to dynamic dependencies. This
// behavior can be overridden with `-C prefer-dynamic`.
// In this test, bar depends on foo and is compiled fully statically despite the available
// `foo` dynamic library. This allows the main binary to be executed in the final step.
// See https://github.com/rust-lang/rust/commit/3036b001276a6e43409b08b7f2334ce72aeeb036
