I fixed `Alias for ` in 42bb5cc502da0e01e5e714800dbec7d13603d399.

GNU ld has very loose parsing rules. It accepts either single-dash or double-dash options. For compatibility we have to do the same. For commonly used single-dash options e.g. -shared -pie (Their compiler driver counterparts use this form), I stick with them. For everything unclear, I use the double dash form.

`-lto-...` is bad because it conflicts with `-l`
