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.
