PATCH 1/1 powerpc: Align p_dyn, p_rela and p_st symbols

The 64bit relocation code places a few symbols in the text segment. These symbols are only 4 byte aligned where they need to be 8 byte aligned. Add an explicit alignment.

Fix the issue I was seeing when booting a LE kernel in a KVM guest on my P7 box.
