The generic version is straightforward. For Hurd, its nanosleep implementation is moved to clock_nanosleep with adjustments from generic unix implementation. The generic clock_nanosleep unix version is also removed since it calls nanosleep. Checked on x86_64-linux-gnu and powerpc64le-linux-gnu. Reviewed-by: Florian Weimer <fweimer@redhat.com>
