How do I codegen rand() so the seed is set off the clock, or otherwise not the same every time?

How can use codegen to make executables that don't make the same random numbers every time? rng('shuffle') and clock() are both unsupported in codegen. For example, if I just want to compile rand() into an executable and get a different number every time it is run (outside of matlab).
