Patch

I've attached a patch that resolves the hang-on-boot on my GTA01Bv4.

The issue was that when stdout was assigned to usbtty and the USB was not
connected, __usbtty_puts() in drivers/serial/usbtty.c would write data into a
256-byte circular buffer and would get stuck in an infinite while() loop when
the buffer filled up.
