Inverting OPTIONS setting in an exp run every now and then could screen
*simple* mistakes. For instance conditionally defined patchfiles,
distfiles, extra patches that don't apply anymore and so on. There is
no way this can ensure that those OPTIONS would even make the port
build but that would not be the intention.
