These concerns might have some merit, but the solution could not possibly
be to only fix this on one platform, because the mechanisms are the same
everywhere. That said, it seems the universal practice is not to put full
sonames into shared libraries, so it seems better that our libraries
follow that practice. Otherwise it will be only a matter of time before
someone comes out of the wood and claims that libraries will full sonames
are a big whatever-else problem.
