Normally, the simulator is notified of absolute pathnames by the _dl_load_hook hook. However, when a relative pathname is used, the simulator may not know that the relative path matches a path that it could figure out in the file system that it has access to. Instead we provide a simplified version of the realpath function so we can pass a plausible absolute pathname to the simulator. Since we're now doing more work at object load time, we also add a guard so we do no work at all if we're not running on the simulator.
