Bug#552621: Unit test failures in upstream antlr 3.2

[Ludovic Claude]

Hello,

I'm packaging the Maven version of antlr. It still has got failures in 
the unit tests, including when I run the build using only upstream 
sources, so I have disabled the unit tests in the Debian build.

You can get the current code for the packaging here:
