I want the build to work with either centos-repo or cgcs-centos-repo.
In many places we will be testing for the existance centos-repo as
the prefered path, then fall back to cgcs-centos-repo as an alternative.
If neither are present, either exit or continue but assuming the new
path is intended.
NOTE: The patch_rebase_1/2/3/4 scripts remain broken, but I hope
to salvage them one day. The current coding assumes content under
centos-repo/cgcs-centos-repo is managed by a git, which is not
currently true.
