This is tradeoff (you reduce code, data may be increased). On the other
side, after this patch (unpacked) executable increased only by 2 bytes.
Moreover, later .cfgInit _array_ may be joined with .cfgInitTail _array_
into one, twice lesser array (with .cfgInitTail as pointer inside this
common array), thus you get bigger reduction.
