GCC for Power64LE supports 128-bit CAS but does not recognize -mcx16 flag.
The current configure.ac#L1459 adds -mcx16 for anything that supports 128-bit CAS and is not icc.
Also different platforms may require different flags to enable 128-bit CAS, maybe we could add a warning when there's no such support?
