Why this name change? I think it may be a little confusing given that "+link"
exists and changes behavior. Similarly, if this comes up for iOS, "_lipo" will
be in the name, when "_shared_library" is probably cleaner there, too. Maybe
just the thin shared_library targets should have a "_arch" in the name instead,
and leave the pre-bundled shared_library output named as _shared_library.

Done.
