rust/tests/run-make/link-arg/rmake.rs

// In 2016, the rustc flag "-C link-arg" was introduced - it can be repeatedly used
// to add single arguments to the linker. This test passes 2 arguments to the linker using it,
// then checks that the compiler's output contains the arguments passed to it.
// This ensures that the compiler successfully parses this flag.
// See https://github.com/rust-lang/rust/pull/36574
