Subject: [PATCH] build.sh: add step to partially copy build artifacts

Add an extra step to copy build artifacts after each build. Some build targets
require additional layers and custom configurations, and subsequent build steps
can overwrite or remove previously generated artifacts once the configuration is
no longer compatible.
