    nptl: Remove private futex optimization [BZ #27304]

    It is effectively used, unexcept for pthread_cond_destroy, where we do
    not want it; see bug 27304.  The internal locks do not support a
    process-shared mode.

    This fixes commit dc6cfdc934db9997c33728082d63552b9eee4563 ("nptl:
    Move pthread_cond_destroy implementation into libc").
