- Add new environment variable AWKLIBPATH to use when searching for shared

libraries.
- Instead of hardcoding the default ".so" suffix for shared libraries, use
autoconf to get the right value for this platform.
- Build and install some of the bundled shared library extensions so that they
will now be available using the default AWKLIBPATH.
