Update.
	* sysdeps/generic/bits/confname.h: Define _PC_REC_INCR_XFER_SIZE,
	_PC_REC_MAX_XFER_SIZE, _PC_REC_MIN_XFER_SIZE, and
	_PC_REC_XFER_ALIGN.
	* sysdeps/posix/pathconf.c (__pathconf): Implement handling of
	_PC_REC_INCR_XFER_SIZE, _PC_REC_MAX_XFER_SIZE,
	_PC_REC_MIN_XFER_SIZE, and _PC_REC_XFER_ALIGN.
