opendingux: Removed inetd.conf

We're using xinetd instead now.
opendingux: Tell dropbear not to refuse login when root password is blank

It is inconsistent that passwordless login is possible with telnet but
not with SSH.
boost: Added a config option to build statically
opendingux: Remove all binutils except for objdump, and DRI drivers
opendingux: GCW0: defconfig: Enable JamVM, NodeJS, static Boost

Also disable ALSA's speaker-test, which takes 1.5 MiB in the rootfs
and is not actually very useful.
