Comments about the patch should go at the top of the patch, preferably.

So, we could avoid a world rebuild by applying the patch in a
powerpc64le-specific build phase instead of adding it to ‘patches’.

Now, I suppose we’re just lucky that this test hasn’t crashed on other
platforms, aren’t we?  In that case, that would call for applying the
patch (or skipping tests, even) unconditionally, thus triggering a world
rebuild on all arches.

Thoughts?
