The failing tests have both old and new trilinos libraries installed.

The failure looks like testing deal.ii linked against the old trilinos 
compiling a test program with the new trilinos, and the cmake files 
likely having related issues.

The release team wants smooth library transitions, but reality is often 
not that smooth and Breaks would technically be correct.

deal.ii autopkgtest was failing also on the other 3 architectures with 
new trilinos and old deal.ii:
