We rebased commit ([WIP] 3rdparty/blobs: Bump for new microcode update for
Intel model 306ax) to the current coreboot master state fb758d420b and
update our build scripts.

We run oldconfig on our config and update it.

We've had a double-quote issue there

also, we use the check for x230 in the flashing scripts now. They have
to be run as root now.

This is included upstream.

We have to do this for the release, see #34

seabios has tagged a release and it's up at coreboot for review in be
included. We'll definitely have it in our next release.

thanks a lot!

Fixes #31
