tests/run-make/staticlib-blank-lib/rmake.rs

// In this test, the static library foo is made blank, which used to cause
// a compilation error. As the compiler now returns Ok upon encountering a blank
// staticlib as of #12379, this test checks that compilation is successful despite
// the blank staticlib.
// See https://github.com/rust-lang/rust/pull/12379
