Neither the LLVM nor clang libraries keep compatibility with previous
versions.

So having the version in the name (rather than using an soversion) is
typically more useful, as then llvm/clang 3.7 and 3.8 can be coinstallable
and you can decide at build time which one you want to build against
(instead of having only a single libclang.so symlink that points to one or
the other).
