Log Message:
-----------
Implement NON_TRANSITIVE case for the Ada bindings.  When obvious
false positives were discounted, ldd -u showed perfect results for the
Ada examples in both the build tree and "traditional" installed
examples tree (that was built and tested with make and pkg-config).

Build and run tests in the build tree and traditional installed
examples tree produced results without obvious errors on Debian
stable.  However, the latest Linux distributions such as Fedora or
Debian unstable have a linker that enforces linking rules much more
stringently than Debian stable so additional tests (and likely some
fixes) are required before -DNON_TRANSITIVE=ON will work for Ada
on those platforms.
