More bugs in 2bsd kernel:

m40.s: the fpp flag is first tested.  Then, however, it is cleared
	when the kernel bss is zeroed.  The fix is to move the test for
	floating point after the bss segment is cleared.

ttynew.c: if both the start and stop characters are the same, and
	we are running in LDECCTQ mode, then a stop hangs the terminal.
	Fix is in ntyinput(); the last if statement should be
		if (tp->t_local&LDECCTQ && tp->t_state&TTSTOP &
		   tun.t_startc != tun.t_stopc)
			return;
