Any reason why the above line has been removed? With the above line
removed nothing under 'purgatory/arch/*/' directory gets compiled. This
makes loading of panic kernel (kexec -p) to fail. I tested it on ppc64
and it fails. Same issue may also exist on other architecture.

Restored the line and able to load panic kernel successfully.
