// If a library is compiled with -C extra-filename, the rust compiler
// will take this into account when searching for libraries. However,
// if that library is then renamed, the rust compiler should fall back
// to its regular library location logic and not immediately fail to find
// the renamed library.
// See https://github.com/rust-lang/rust/pull/49253
