1) Restore the ability to build CGI as a shared library
2) Correct make dependency rule so that the jar files are included
3) Search for jar executable, and use it, if found
Left TODO: actually build the shared libraries
- added support for externally built modules,
- improved support for in-tree shared modules,
- fixed diversion bugs,
- configure displays some informative messages,
- faster static build
(libtool isn't used anymore for compiling non-PIC objects),
- dependencies comparable to automake's without requiring GNU make or GCC,
- working make clean for non-GNU makes.
