[PATCH] powerpc: Align p_end

[Anton Blanchard]

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.
