Dropping dependencies of a -no-undefined library

[Alexandre Oliva]

We shouldn't attempt to build a shared library in case we drop
dependencies.  It will either fail or build an incomplete library.
Here's a patch that fixes this.  Ok to install?

        * ltmain.in: When dropping dependencies of a -no-undefined
        library, give up on building a shared library.
