If we're going to share a single set of source files for ppc64le
and ppc64 (which makes sense) then I think we should use ARCH=ppc64
for that, and rename the 'ppc64le' source files to 'ppc64'.
The rest of these patches look OK.

Incidentally, maybe we should just drop support for
specifying ARCH= manually to configure. I can't really
see a use case where the auto-detection won't do the
right thing.
