I can only repeat what I mentioned in comment 2, which is that these
directories should be created by mtree, during the earlier stages (e.g. before
"stage 3: cross tools").

If that does not happen for you, can you please check whether your source tree
is cleanly checked out, without any modifications?

If it still fails, can you post a full buildworld log somewhere?
