UBUNTU: [Config] Restore prepare-% target

It turns out that some tossers like to shortcut the process during development.
A common sequence for a quick compile test is to preapre the tree, copy the
.config, then perform an in-tree compile. For example,

fakeroot debian/rules clean prepare-generic
cp debian/build/build-generic/.config .
make oldconfig scripts prepare
make M=`pwd`/fs/ext4
