[PATCH] Update RPATH to make loading libjawt possible

[Kumar Srinivasan]

Hi Anthony, Omair.

Here is the patch for the test, this will live in test/tools/launcher, 
also I don't have access
to a MacOS system, appreciate if you can add this otherwise I will file 
a bug and add
the macosx case later on.

Thanks

Kumar
