xihh:
  [x] I approve of licensing fullpkg, fullpkg-build, mips-add and
      toru-utils under the GNU GPLv3, or (at the users' option) any
      later version. (Unspecified -> GPLv3+)
  [x] I approve of re-licensing toru from the GNU GPLv3 exclusively to
      the GNU GPLv3, or at the users' option any later version. (GPLv3
      -> GPLv3+)
  [x] I approve of re-licensing libremessages, librechroot, and
      libremakepkg from the GNU GPLv3 or any later version to the GNU
      GPLv2 or any later version. (GPLv3+ -> GPLv2+)
