[PATCH] kexec: Fix the purgatory Makefile to build arch specific purgatory code.

[Mahesh J Salgaonkar]

From: Mahesh Salgaonkar <mahesh at linux.vnet.ibm.com>

The latest commit 5e48916 has removed a line from purgatory/Makefile that was
responsible for building arch specific purgatory code. This causes kexec -p
(loading of panic kernel) to fail. This patch reverts the deleted line.

Verified this fix on x86_64 and ppc64.
