contrib/buildsystems: error out on unknown option

One time too many did this developer call the `generate` script passing
a `--make-out=<PATH>` option that was happily ignored (because there
should be a space, not an equal sign, between `--make-out` and the
path).

And one time too many, this script not only ignored it but did not even
complain. Let's fix that.
