[PATCH] 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. Signed-off-by: Anton Blanchard

[PATCH] powerpc: Align p_end

p_end is an 8 byte value embedded in the text section. This means it is only 4 byte aligned when it should be 8 byte aligned. Fix this by adding an explicit alignment. This fixes an issue where POWER7 little endian builds with CONFIG_RELOCATABLE=y fail to boot. Signed-off-by: Anton Blanchard
