tests/run-make/pass-linker-flags-from-dep/rmake.rs

// A similar test to pass-linker-flags, testing that the `-l link-arg` flag
// respects the order relative to other `-l` flags, but this time, the flags
// are passed on the compilation of a dependency. This test checks that the
// downstream compiled binary contains the linker arguments of the dependency,
// and in the correct order.
// See https://github.com/rust-lang/rust/issues/99427
