Some systems (like 32-bit RISC-V) only have the 64-bit time_t versions
of syscalls. So handle the 32-bit time_t version of those being
undefined.

This seems a little ugly, as it'll blow up when neither is defined. Some
#if/#error type stuff seemed uglier, though, and that's the best I could come
up with. I figure anyone without either flavor of futex call is probably deep
enough in the weeds to just figure what blows up here...
