Alex Richardson ec45ce6222 Make mkioctls script work on Linux and MacOS
Using find -s  will not work with the Linux or MacOS find command. We pipe
to sort instead since the only real requirement here is that the order
stays the same. While I am touching this file I also fixed a `==` construct
which is not supported by POSIX sh but appears to work on FreeBSD.
