We have fixed most build failures related to the octave 4.4 transition. We
think the four remaining packages should be removed from testing:
- libsbml: FTBFS for reasons not related to the transition (#901455), has
another RC bug (#896531), scheduled for removal on July 4th;
- octave-{odepkg,tisean,ltfat}: these packages are maintained by the Debian
Octave Group, and we currently don't have a patch to fix them. They're all
leaf packages, except octave-odepkg, whose reverse dependency octave-ocs will
therefore needs to be removed too.
