[Bug java/16200] New: gcj generates dependencies on the full contents of the extensions directory

If you build some java code, and have the compiler generate dependency info,
you'll see that the depencies include all jar files in the extensions directory.
 For instance, when building libgcj with jars in my install areas extensions
directory, I get dependency info like this:

etc
etc

I don't think any of those jar files should be in this list.
