powerpc: Align p_end
commit 286e4f90a72c0b0621dde0294af6ed4b0baddabb upstream.
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.
