powerpc: allyesconfig should not select CONFIG_CPU_LITTLE_ENDIAN
Stephen reported a failure in an allyesconfig build. CONFIG_CPU_LITTLE_ENDIAN=y gets set but his toolchain is not new enough to support little endian. We really want to default to a big endian build; Ben suggested using a choice which defaults to CPU_BIG_ENDIAN.

be built.

Note that if cross compiling a little endian kernel,
CROSS_COMPILE must point to a toolchain capable of targeting
little endian powerpc.
