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.

One needs to look at the diff between versions. If in doubt, just
always bump.
