This allows us to preserve the various product definitions during the compile phase, and allows us to select the product in the link phase. This allows compiled files to remain product-independent, so that they do not need to be recompiled when switching targets. Bug:25958912 Change-Id: Iaa7eed25c834b67a39cdc9be43613e8b5ab6cdd7
