This is a set of buildsystem patches to allow libgnome-java to be built on OpenSolaris nevada build48 and above [currently this build uses Gnome 2.14, but will be bumped to Gnome 2.16 shortly].

Changes for the following:
1. Running examples: changes to runExample.sh.in making tests work on OpenSolaris
2. Need gnome2-java-uninstalled.pc.in for common routines for Java-GNOME bindings, Not installed. Needed when building meta/uber packages.
3. Configure --with_javadir is meant to be a supported configure option to tell the build where to put generated jar files, but had some hard coded path bugs and was not being picked up in generated .pc file.
4. Generating Javadoc on OpenSolaris - problem with use of "find -mindep". Not supported on this OS, simple generic workaround added. Also added missing classpath to remove build errors.
5. Added support to create src jar, patterned after support already commited to glib-java.
6. Need to change where doc base dir is set in the build, as we wanted to put it in a different location on OpenSolaris. Currently defaulting to ${datadir/doc}. Added configure option --with_docbasedir to support this.
