As much as I am eager to move everything, quickly, over to LTO by
default, I think the problems that we've seen thus far show it's best to
really make it an explicit enable per board at least for the first
release or two.  Once we've hopefully gotten more boards tested and
enabled we can see what makes sense for defaults, give a release worth
of heads up, and then go.
