    Subject[patch 10/28] posix-cpu-timers: Remove the stub nanosleep functions
    CLOCK_THREAD_CPUTIME_ID implements stub functions for nanosleep and
    nanosleep_restart, which return -EINVAL. That return value is
    wrong. The correct return value is -ENOTSUP.

    Remove the stubs and let the new dispatch code return the correct
    error code.
