tests/run-make/lto-dylib-dep/rmake.rs

// Compiling with link-time-optimizations (LTO) would previously run into an internal
// compiler error (ICE) if a dylib was passed as a required library. This was due to a
// misplaced assert! call in the compiler, which is now removed. This test checks that
// this bug does not make a resurgence and that dylib+lto compilation succeeds.
// See https://github.com/rust-lang/rust/issues/59137
