When trying to build an overcloud image on ppc64le tripleo/DIB attempts to build an amd64 image.

openstack-tripleo-common-7.6.3-0.20171010234827.el7ost.noarch


Steps to Reproduce:
1. Create a ppc64le 'input image':
   https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=14309272
2. Create a ppc64le 'utility image'
   https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=14309274
3. Boot the utility image and import the input image from step 1
4. Use the TDL template from http://pkgs.devel.redhat.com/cgit/rpms/rhosp-director-images/tree/overcloud-full.tdl?h=rhos-12.0-rhel-7 to transform the simple input image into an overcloud image

Actual results:

openstack overcloud image builds fails with:

"""

"""

Expected results:

A generated overcloud image.


Additional info

The are a couple of options here
1. Backport https://review.openstack.org/#/c/489476/ to pike upstream and the import the new SHA into the RHOS packaging
2. use scripts in rhosp-director-images to do this translation.
