// When the compiler is performing link time optimization, it will
// need to copy the original rlib file, set the copy's permissions to read/write,
// and modify that copy - even if the original
// file is read-only. This test creates a read-only rlib, and checks that
// compilation with LTO succeeds.
// See https://github.com/rust-lang/rust/pull/17619
