crc32 on ppc64 (8131048)

[Volker Simonis]

Hi Vladimir,

did you mixed up UseCRC32CIntrinsics with UseCRC32Intrinsics (without the
"C" in the middle)?

We have only implemented CRC32 until now but not CRC32C.

I was confused myself after your question and only found the solution after
using "grep" with copy and pasting "UseCRC32CIntrinsics".

Regards,
Volker
