trilinos without explicit instantiations

It turns out explicit instantiations have the following problems:
- it confuses linkers like gold leading to missing instantiations
- breaks compilation on OSX ARM (symbols with wrong arch)
- it is likely related to a big bloat in library size

Disable them for now...
