Can't use bootstrap images for arm build
Context
At Endless we're trying to build our SDK (based on gnome and freedesktop) for arm in addition to aarch64. But the build fails immediately because the PreBootstrap image isn't wired up.
Description
-
Allow arm builds to use the PreBootstrap image ostrees.
Acceptance Criteria
ARM builds can be made using bst -o target_arch arm -o bootstrap_build_arch arm
