I think this replay command needs to specify the extracted output filename with
`file=...`. Without that, `llvm-offload-binary` chooses its default name, like
`input-triple-arch.0.o`, but the later printed `clang` command uses the
wrapper-created temp name, like `input-triple-arch.o`. Then the printed command
sequence cannot be copied and rerun as-is.
