Sorry, I misunderstood.

I propose that prepare.sh test for boehm_gc/.git for this purpose.
Optionally it could be more helpful and do something like:

If not boehm_gc/.git exists then
    if boehm_gc/* exists then
        Tell user that they need to manually remove boehm_gc/* and re-run
        ./prepare.sh
        exit 1
    else
        setup git submodules.
    end if
end if
setup autotools.

However that may be unnecessary because once everyone transitions this
shouldn't be a problem again.
