ppc64le iso boot failure message screenshot

Description of problem:
When trying to boot latest ppc64le iso from Rawhide nightly composes, it fails to boot. Error message appears on screen is:
  "( 700 ) Program Exception [ 0 ]".

Screenshot of message printed during boot failure is also available in this bugzilla attachment.

Version-Release number of selected component (if applicable): grub2-2.02-0.34.fc26.ppc64le.rpm

Steps to Reproduce:
1. Get a ppc64le ISO from Rawhide nightly composes e.g. https://kojipkgs.fedoraproject.org/compose/rawhide/Fedora-Rawhide-20161128.n.0/compose/Server/ppc64le/iso/
2. Boot from downloaded ISO and error will appear during boot process

Actual results:
Fails to boot

Expected results:
Should boot successfully

Additional info: 
1. To confirm the problem, I updated grub2 package on my F25, ppc64le box from grub2-2.02-0.34.fc24.ppc64le.rpm to grub2-2.02-0.34.fc26.ppc64le.rpm. Also updated grub2-tools-2.02-0.34.fc24.ppc64le.rpm to grub2-tools-2.02-0.34.fc26.ppc64le.rpm. Then ran command "grub2-install" and rebooted system. Got same Program Exception error during boot.
2. It might be related to BZ#1334672 and possibly fixes made in F24 dist-git branch has not been merged to master branch.

Peter suggested to use a regex in the sed command swapping the default -mcpu to power6

I confirm that this patch solves the ppc64le boot issue.

Updated grub2 sub-packages in ppc64le box with sub-packages available in this scratch build. Ran grub2-install command after update and rebooted system. It works fine.
