IMO that's a valid fix for buster, but does not fix the underlying issue
for sid / buster+1.

The next time a newer version of eigen3 is uploaded, you'll have the
same "problem" all over again: adjust the build dep and upload to get a
corresponding rebuild.
Updating eigen3 renders ceres and similar packages unusable until
rebuilt, please read through the discussion in #868355 to understand
what I mean.

The eigen3 maintainer and I are happy to simply rebuild affected
packages after every eigen3 update, but Emilio considers it an upstream bug.
Unfortunately I could not find anybody able to shed more light on the
eigen3 topic.
