Don't allow a module built without versions altogether to be inserted into a kernel which expects modversions. modprobe --force will strip vermagic as well as modversions, so it won't be effected, but this will make sure that a non-CONFIG_MODVERSIONS module won't be accidentally inserted into a CONFIG_MODVERSIONS kernel.
