[PATCH v1 2/3][makedumpfile][ppc64] Rename the __powerpc__ macro to __powerpc64__ for PPC64

[Suzuki K. Poulose]

Makedumpfile uses __powerpc__ as the value of ARCH to control the PPC64
specfic definitions. Rename this to __powerpc64__ for a better readability
of the code as the support for ppc32 will be introduced in the later series.
We could use __powerpc32__ for PPC32.
