This test doesn't work for me (and note the System.out.println which
probably shouldn't be there). It gives the following output:

I assume you have something in your tree that generates
the /home/mark/src/frysk-obj/frysk-core/frysk/pkglibdir/test-sysroot/
directory. But I couldn't figure out how to properly do that.

Could you take a look? And maybe add some documentation on how a sysroot
dir should look like, how to generate one by hand?

Thanks,

Mark
