This isn't a problem. It occurs (I think) because there are commands in
/etc/inittab to initialise the loopback interface, which get executed
again when "ifup -a" runs from the /etc/init.d/S40network initscript.
You can ignore this error.

It means there is nothing listening for your command because...

....it looks like you are not running a getty on ttyS0 (or whatever your
console is on).

In "make menuconfig", under Target Options --> Generic serial port
config, there is the option to set the serial port to run a getty on. If
you set this properly, you should end up with a line (uncommented) in
/etc/inittab that reads:

ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100 # GENERIC_SERIAL

This line will allow you to log into the system through minicom. You
should see the same prompt there you showed above that was on the LCD.
