I don't anticipate that to be a problem. And before they do, and/or
if you are dealing with a system where the kernel has been upgraded,
but not libc, you have your choice of either sticking with the
binary_sysctl approach, or calling getrandom directly using the
syscall method; and in that case, whether we use getrandom() or
provide an exact getentropy() replacement system call isn't that much
difference, since you'd have to have Linux-specific workaround code
anyway....
