	* libio/genops.c (_IO_flush_all_lockp): New function.  The same code
	as the old _IO_flush_all but lock only if parameter is nonzero.
	(_IO_flush_all): Call _IO_flush_all_lockp with 1 as parameter.
	* libio/libioP.h: Add prototype for _IO_flush_all_lockp.
	* sysdeps/generic/abort.c (fflush): Define to _IO_flush_all_lockp(0)
	if libio is used.
