In this case, the exact extern crate isn't very important. This is part of the changes needed to address the spurious failures from a main test `../removing-extern-crate.rs` being both an auxiliary and a main test file, causing fs races due to multiple `rustc` processes in multiple test threads trying to build the main test file both as a main test and also as an auxiliary at around the same time.
