That prunes from the bottom up, so it'll also remove directories that only
contain directories that are empty, and so on recursively, which may not
be the goal.
If the goal is only to remove the empty leaf directories, then use -prune
to tell find to not recurse into the directory you're removing:
find /tmp/foo -type d -empty -prune -exec rmdir -- {} \;

That works, but is dependent on the target hierarchy only being 2 levels
deep, so it's harder to generalize.
