Last time I checked, ioctl was defined in libc. Yeah, it's just a
lightweight cover for a kernel call, but that's hardly unusual.
There does need to be a systematic way of getting the defined constants
for ioctl, but that's different from removing ioctl from libc.
[And, in principle, libc *could* map constants from one set of values to
another...]
