It looks like ppc64le fails to bootstrap with the same comparison 
failure aarch64 fails with, so I need to take a look at ppc64le regardless.

However, for your particular problem, I wonder if this was a preexisting 
condition.  Would you mind reproducing your problem without my 
debug-early patchset, but with the attached patch?

The commit prior to debug-early is:

	git commit d51560f9afc5c8a826bcfa6fc90a96156b623559
	trunk@224160

The attached patch adds the sanity check, but without the debug-early 
work.  If you still get a failure, this is a pre-existing bug.

Thanks.
Aldy
