The intent was to save also the SDK (toolchain), except it does not
currently work.
But this raises a more high-level question about what we want to save
here: target packages, host packages (toolchain and others), BR sources,
BR .config? I think the right answer is "all of them", but I've put it
on my list of issues to be discussed in the BDD.

Ops, this is the result of the massive rebases I did before posting.
Moved to the right patch, thanks.
