Update.

Update.

	* sysdeps/unix/sysv/linux/speed.c (IBAUD0): New definition.  Bit
	set in c_iflag if cfsetispeed is call with SPEED set to zero.
	(cfgetispeed): Return zero if prior if IBAUD0 is set.
	(cfsetospeed): Clear IBAUD0 bit.
	(cfgetispeed): Set IBAUD0 bit if necessary.
	* sysdeps/unix/sysv/linux/tcsetattr.c (tcsetattr): Clear
	the IBAUD0 bit in c_iflag when making the system call.
	Work around a Linux kernel bug which silently changes the
	PARENB/CREAD/CSIZE bits in c_cflag on pty.
	Based on a patch by H.J. Lu <hjl@gnu.org>.
	* Makeconfig (link-libc-static): Don't use link-libc since this
	includes the shared object.  Use gnulib only.
