IMO the guality testsuite is not really appropriate for debug info issues,
it's too brittle, has a low signal-over-noise ratio and nobody really cares
about it. And, given that most people already don't care about the regular
gnat.dg testsuite, I think that literally nobody will about gnat.dg/guality.
Given that only AdaCore's folks work on Ada debug info issues in practice and
that they run the GDB testsuite, I don't see any real need for it.
