To give everyone an overview of the current issues (on release archs), I've
roughly grouped the test failures by topic and arch below.

As some of these tests point to serious issues, just disabling is
not the "correct" fix there.

Current Failures:

(I have not seen this one on my build host yet and also not on the
-3 build, so maybe this is a transient problem.)

There are additional failures on non-release archs, but let's fix
the release archs first.

Re: [Stretch] Status for architecture qualification

[Brock Wittrock]

I run all sorts of PowerPC machines with various versions of Debian and I
don't see that coming to end anytime soon.  These are excellent and
reliable machines.  Biggest issues/hurdles are just graphics at the moment
for both ATI/AMD and Nvidia cards, but even if that is never resolved/fixed
or performance dwindles to nothing, I will continue to use these machines
in text/console only mode if I have to.  Please do not drop this
architecture!

I hope that my iBook G3 will serve me for years to come! Low power 
consumption fanless with a SSD disk make superquiet and quite nice!
