    Auto merge of #46592 - o01eg:fix-45345, r=alexcrichton

    Fix 45345

    There is a fix for https://github.com/rust-lang/rust/issues/45345

    It re-introduces `CFG_LIBDIR_RELATIVE` which was broken when migration from `configure` script to `x.py`.

    Other commits fix errors which happen after rustbuild cleanups.
