interesting. the trilinos-teuchos12 package depends on
binutils (>= 2.26), binutils (<< 2.27)

if that's correct, we shouldn't link libtrilinos_teuchoscore.so to a
particular revision of libbfd-2.26-system.so. how would that be
possible?

otoh, if libbfd-2.26.1-system.so
- is meant to replace libbfd-2.26-system.so, shouldn't there be a
  symlink?
- is NOT meant to provide libbfd-2.26-system.so, then why are these not
  coinstallable?

I'm not trying to argue that this is a bug in binutils, i just don't
understand. my idea would be to change the binutils dependency to
(=2.26), but that feels a bit silly (isn't that dependency automatic?).
