// This is an unfortunate off-by-1 caused (possibly) by the fact that Miri doesn't have an
// "assemble" step like rustc does that would cross the stage boundary. We can't use
// `add_rustc_lib_path` as that's a NOP on Windows but we do need these libraries added to
// the PATH due to the stage mismatch.
