Because it is so easy to change the ABI with just one configure option,
explicitly mark our build with a vendor tag.
(We do the same in windows:mingw: where this issue is even more pressing.)

In addition, because wxWidgets changes the ABI midway (for example,
did so between 3.0.1 and 3.0.2) without changing the SONAME, we have
to do it. As we have a vendor suffix, no filename conflicts can occur.

The ABI may not always change, so one needs to look at the diff
between versions for whether or not soversion.diff needs an update.
