If my understanding is correct, even if the default layout changed, the
previous layout is still there so you can use the "--layout=<layout>"
option of Boost 1.66's b2,
which I just realized is not documented online yet, so just look at the
help info. I'm not totally sure but I think you need "versioned" layout to
get the previous layout.
