// The --extern flag can override the default crate search of
// the compiler and directly fetch a given path. There are a few rules
// to follow: for example, there can't be more than one rlib, the crates must
// be valid ("no-exist" in this test), and private crates can't be loaded
// as non-private. This test checks that these rules are enforced.
