tests/run-make/raw-dylib-inline-cross-dylib/rmake.rs

// When we generate the import library for a dylib or bin crate, we should generate it
// for the symbols both for the current crate and all upstream crates. This allows for
// using the link kind `raw-dylib` inside inline functions successfully. This test checks
// that the import symbols in the object files match this convention, and that execution
// of the binary results in all function names exported successfully.
// See https://github.com/rust-lang/rust/pull/102988
