Two improvements: shared objects, and configuring git-pull:

  git clone git://gitorious.org/qt/qt.git qtrepo
  git init qt46
  PARENT_GIT=$(pwd)/qtrepo/.git
  cd qt46

  # use of shared objects - tell git where to find the "missing" objects
  cat $PARENT_GIT/objects > .git/objects/info/alternates

  # setup of git pull
  cat <<EOF >> .git/config
[remote "parent"]
  url = $PARENT_GIT
[branch "master"]
  remote = parent
  merge = refs/remotes/origin/4.6
EOF

  # done!
  git pull

Repeat for 4.7.

If you want to go one step further and track these repos, you could look at git-submodule or git-subtree.
