Unhelpful configuration error message

Something in my `pyoxidizer.bzl` file is wrong:

```
% RUST_BACKTRACE=1 pyoxidizer --verbose build
error: Extraneous parameter passed to function call
```

Unfortunately, nothing in that output gives me any clue on where to look for the problem or how to fix it. I can't find that error message in the PyOxidizer code. Is it in a library? Is it Rust? Is it Starlark?

Reproduce the reported `RUST_BACKTRACE=1 pyoxidizer --verbose build` command with the problematic `pyoxidizer.bzl` configuration and trace where the “Extraneous parameter passed to function call” output originates. Done means the configuration error identifies where the problem is and provides useful guidance for fixing it.
