I don't really understand this ifdef. What does this get? Since you
don't need cryptographic guarantees, it gets you pretty much nothing
(while it does have costs since CSPRNG are often slower due to
cryptographic nature).

So this is just more code to get nothing in return. Not very suckless.
And not sensible in general either IMO.
