No, the key needs to be built before the kernel is built, since the
public part (for verification) needs to be built into the kernel (and
we don't want to make "make install" complicated).

Making it less verbose is clearly an option, though. Right now I like
seeing it just to see when the key gets recreated and so people are
aware of it, but the excitement of that will certainly pall quickly
enough ;)
