snapshot modules require the list of static libs to find the NOTICE files for the snapshot modules. snapshot binaries must include static_executable property to check if non static binaries have libc as a static lib. Bug: 190690041 Test: Check NOTICE for libaudiopreprocessing.so built from snapshots. Change-Id: I53f7549a158ab27ada87833a3f4d58620aa7c3cf
