WL#4361: NDB/J build should be driven more by ANT

Affects: Connector/NDB-0.7   —   Status: Un-Assigned   —   Priority: Medium

Although autoconf/automake is the standard for building C code in the *nix
world, ANT is the standard mechanism for building Java. Where possible, more of
the build for Java should be driven by ANT, similar to how Python is using
setuptools and Perl uses MakeMaker.
