Subject: [PATCH] Workaround for build failure when building from a clean
 source tree.

The build fails when building from a clean source tree, because the
CuckooChessEngine.jar file does not exist. This commit adds a workaround,
but you have to build twice to get the CuckooChess.jar file to be built.
