Joel Stanley fdb23693a4 arch/powerpc: Enable powerpc64le only on CPUs that support it
Invalid configurations lead to build failures, such as trying to enable
ppc64le for the ppc970:

  http://autobuild.buildroot.net/results/fda886768fce25ccd9b52b635ff5b13da7ba2d0c/

In order to run a ppc64le userspace a kernel that runs in this mode is
required. The only CPU supported in buildroot that can boot a ppc64le
kernel is Power8, so mark all of the other 64-bit capable CPUs as not
supporting ppc64le. For Power7, the situation is not so clear, but there
are anyway no commercially available CPUs for that architecture so it
doesn't matter much either way. Let's be safe and disable LE on that one
as well.

This drops the comment about libc, which is true but doesn't tell the
whole story.

Note that we use positive logic for the new conditions, while the rest
of the file uses negative logic. We'll fix that for the rest of the file
in a follow-up patch.
