I found https://patchwork.kernel.org/patch/9442211/ today and I see that
it was brought up again just before I sent my patch.  I just want to
point out that 9442211 doesn't address arm, arc, and sh and they will
still not have a functional rpm build target.  This is at least probably
important for arm.  Of course all of those could also be addressed with
a patch similar to 9442211, and my main concern is making sure
everything gets fixed one way or another.  Thanks!
