The good news is that Validation.pm already has a loop over the 
installed dylibs in a .deb, excluding bundles, so adding an extra test 
won't be too difficult.

The bad news is that my test case (libtcd-shlibs on 10.10 with and 
without the PatchScript) didn't seem to give different "otool -H " 
output whether or not -flat_namespace was used.
