What depends on BASE-VER sure, that is bumped automatically and should track
the gcc version.  But the soname, which is an unrelated number, there is no
point to bump it.  If you have a packaging issue, just solve it on the
packaging side, but really there is no point to yearly bump a soname of
something that doesn't change at all (and is really dead project for many
years).
