MOTD enabled by default as the manpage says (#87) The man page (https://github.com/mkj/dropbear/blob/master/dropbear.8) says MOTD will be printed by default for any login shell, but it was disabled at compile time. Probably happened by accident when this code was moved from `options.h` to `default_options.h`.
