Usage: build-redbear-wifictl-redox.sh [cargo build args...]

This helper ensures the repository's Redox cross-linker directory is on PATH before invoking
`cargo build --target x86_64-unknown-redox` for `redbear-wifictl`.

Examples:
  ./local/scripts/build-redbear-wifictl-redox.sh
  ./local/scripts/build-redbear-wifictl-redox.sh --release
