To enable building with coverage, the environment variable NATIVE_COVERAGE must be set to true. Set `LOCAL_NATIVE_COVERAGE := true` to generate coverage information for a given component. This is currently not supported for clang (b/17574078, b/17583330). If static library A is included in a binary B (dynamic or static executable, or shared library), and A is built with coverage information, B is required to link with libgcov.a. Since the make does not offer a good way to track this dependency, link libgcov.a even if LOCAL_NATIVE_COVERAGE is not set (but still guarded by NATIVE_COVERAGE). This ensures that all of the libgcov dependencies will always be resolved, and causes no change in the resulting binary if coverage is not used.
