Nothing changed between 1.2.5 and 1.2.6 with regards to depending on libibverbs.

Ok then I need to check what we did differently when installing both versions.

The mpicc wrapper from 1.2.6 links -libverbs.
(It shows up with mpicc -V).

This suggests that perhaps 1.2.6 was configured with --enable-static or --disable-dlopen. If either of these two options were used, OMPI will suck all the plugins to become part of libmpi (and friends), and therefore the plugins' dependencies will therefore become dependencies of libmpi (and friends).
