I've updated the PR to pass along this already parsed target platform to the `DefaultImageBuilder`. This code is new to me and I think I made sure (by checking references and the package names) that I only updated the internal classes without impacting any user facing APIs. If however, this impacts any user facing API, please do let me know.
