Don't condition RUSTDOC_LIBDIR on `--no-doc`
In d94e7ff065, `rustdoc_path` was changed to ignore `want_rustdoc` (which is just whether `--no-doc` was passed). But RUSTDOC_LIBDIR wasn't kept in sync. Rather than trying to keep `rustdoc_path` in sync with `RUSTDOC_LIBDIR`, just pass LIBDIR to the rustc shim unconditionally.
This fix allows calling `ensure(doc::Step)` from a non-doc top-level Step, even if `--no-doc` was present in the command line.
This directory contains some source code for the Rust project, including:
- The bootstrapping build system
- Various submodules for tools, like cargo, tidy, etc.
For more information on how various parts of the compiler work, see the rustc dev guide.
