[PATCH] D137511: [PPC] Undefine __ppc64__ to match GCC

[Nemanja Ivanovic via Phabricator via cfe-commits]

nemanjai added a comment.

As mentioned by @q66 above, this can't go in until usage of this macro in the Clang/LLVM codebase is fixed. Looks like the uses in `clang/lib/Headers/ppc_wrappers` and some of the uses in `libcxx` and `libunwind` must be fixed while others should probably also be fixed to avoid confusion.
