tests/run-make/archive-duplicate-names/rmake.rs

// When two object archives with the same filename are present, an iterator is supposed to
// inspect each object, recognize the duplication and extract each one to a different directory.
// This test checks that this duplicate handling behaviour has not been broken.
// See https://github.com/rust-lang/rust/pull/24439

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