tests/run-make/extern-multiple-copies2/rmake.rs

// Almost identical to `extern-multiple-copies`, but with a variation in the --extern calls
// and the addition of #[macro_use] in the rust code files, which used to break --extern
// until #33625.
// In this test, the rust library foo1 exists in two different locations, but only one
// is required by the --extern flag. This test checks that the copy is ignored (as --extern
// demands fetching only the original instance of foo1) and that no error is emitted, resulting
// in successful compilation.
