[PATCH] D64301: Use `ln -n` to prevent forming a symlink cycle, instead of rm'ing the source

[Hubert Tong via Phabricator via cfe-commits]

hubert.reinterpretcast added a comment.

`ln -n` is not a standard option that is portably supported. I'll be restoring the use of `rm` (with `-f` instead of `-rf`) and the associated comment for removing `%t.fake`.
