powerpc/64: whitelist unresolved modversions CRCs

These are a symptom of CRC generation failure in generic build code, and not powerpc specific.

---

Hi Michal,

Please merge this via your trees with Al's patches. I have a patch that can catch crc generation failure generically, and both Arnd and I have some ideas to fix crc generation for .S exports. This should get powerpc building again with your tree.

Thanks,
Nick

Hi Nick,

OK, so I will use this as a merge fix patch for the kbuild tree today (instead of the revert I have been doing).
