* Updated configure/make scripts to resolve various issues.

- Added detection whether or not -fPIC switch is required when compiling shared objects (plug-ins) to resolve compile issues on 64-bit platforms (topic:208746).
- Native 'strnlen' implementations are now detected and disable the one in strlib (bugreport:1261).
- Define 'DB_MANUAL_CAST_TO_UNION' is now set when necessary (bugreport:1261).
