This will disable futexes if running under a kernel older than 5.1, 
though, which doesn't seem ideal. It should be relatively easy to keep 
the 32-bit wait as a fall-back path.

I also don't think we want to check __USE_TIME_BITS64, since that's an 
internal symbol.

I think it may be easiest just to manually define the timespec structure(s).
