	* sysdeps/sh/tcb-offsets.sym: Add PRIVATE_FUTEX.
	* sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h: Include endian.h.
	Split __flags into __flags, __shared, __pad1 and __pad2.
	* sysdeps/unix/sysv/linux/sh/libc-lowlevellock.S: Use private
        futexes if they are available.
	* sysdeps/unix/sysv/linux/sh/lowlevellock.S: Adjust so that change
        in libc-lowlevellock.S allow using private futexes.
	* sysdeps/unix/sysv/linux/sh/lowlevellock.h: Define
	FUTEX_PRIVATE_FLAG.  Add additional parameter to lll_futex_wait,
	lll_futex_timed_wait and lll_futex_wake.  Change lll_futex_wait
	to call lll_futex_timed_wait.  Add lll_private_futex_wait,
	lll_private_futex_timed_wait and lll_private_futex_wake.
	(lll_robust_mutex_unlock): Fix typo.
	* sysdeps/unix/sysv/linux/sh/pthread_barrier_wait.S: Use private
        field in futex command setup.
	* sysdeps/unix/sysv/linux/sh/pthread_cond_timedwait.S: Use
	COND_NWAITERS_SHIFT instead of COND_CLOCK_BITS.
	* sysdeps/unix/sysv/linux/sh/pthread_cond_wait.S: Likewise.
