consider giving precedence to `--config` over RUST_BOOTSTRAP_CONFIG

https://github.com/rust-lang/rust/blob/7b43cfc9b25ac4a906bd56d32d3111085dd9e6a1/src/bootstrap/bootstrap.py#L1224-L1228
It seems pretty strange to me that the env variable would take precedence over --config. It would be nice to switch the precedence.

	# Read from `RUST_BOOTSTRAP_CONFIG`, then `--config`, then fallback to `config.toml` (if it
	# exists).
	toml_path = os.getenv('RUST_BOOTSTRAP_CONFIG') or args.config
	if not toml_path and os.path.exists('config.toml'):
	toml_path = 'config.toml'
