[Buildroot] Buildroot for powerpc, no prompt + OpenSSH login

[Sebastian <bastisoft@arcor.de>]

Hello,

as far as I know SSH logins are not allowed unless there is a password 
set. To not show the attacker that there is no password, the prompt is 
still shown.

To connect through SSH, you need to set a password (passwd). Then it 
should work. Preferably use another user and "su" to do administration.

Hope this helps,

Sebastian
