Trying to install busybox with hardlinks and a custom PREFIX will fail for applets not in the /bin directory, because relative pathnames are used. applets/install.sh is *supposed to* use the absolute pathname for hardlinks but it fails to do so because the wrong check is used in the if statement. Patch below fixes it.
