The RNG always mixes in the Linux version extremely early in boot. It also always includes a cycle counter, not only during early boot, but each and every time it is invoked prior to being fully initialized. Together, this means that the use of additional xors inside of the various stackprotector.h files is superfluous and over-complicated. Instead, we can get exactly the same thing, but better, by just calling `get_random_canary()`.
