libffi-tarballs

After the libffi-tarballs submodule was added, I did a ./sync-all pull, a ./sync-all get, and a git submodule update. Everything builds just fine, but I get this answer from git status: # On branch master # Untracked files: # (use "git add <file>..." to include in what will be committed) # # libffi-tarballs/ nothing added to commit but untracked files present (use "git add" to track) Is this expected? How can I fix this? Thanks! Richard
