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
