`x test --stage 1 tests/rustdoc{,-ui}` fails when download-rustc is enabled

[jyn514]

I tried this code: ./configure --set download-rustc && x test --stage 1 rustdoc-ui

I expected to see this happen: All tests pass

Instead, this happened:

warning: `download-rustc` does nothing when building stage1 tools; consider using `--stage 2` instead

HEAD is 39c6804

I think this is pretty low priority, I don't know why anyone would need to run x test --stage 1 when download-rustc is enabled.
