Android static libraries are like APKs but they contain much more debugging and source information. We need to treat them differently in 3 ways: 1) When building a static library, we skip things like ID assignment and product/config stripping. Source information is emitted as well. 2) When building a static library and linking against another static library, we don't want to merge, we want to simply reference. 3) When building an app that uses static libraries, we want to merge the static library under the same package with or without mangling.
