Set up rules to build shared libraries for TARGET_2ND_ARCH The rules for the 2nd arch are set up in the second inclusion of shared_library_internal.mk. Intermediate fils of libfoo of the 2nd arch will be built into $(PRODUCT_OUT)/obj_$(TARGET_2ND_ARCH)/SHARED_LIBRARIES/libfoo_intermediates/ and the built libfoo.so will be in $(PRODUCT_OUT)/obj_$(TARGET_2ND_ARCH)/lib.

add support for LOCAL_MODULE_STEM_32 and LOCAL_MODULE_STEM_64 Some executables will need to be built for both 32-bit and 64-bit. For linker/linker64, debuggerd/debuggerd64, and a few more, they will be installed in the same path (/system/bin), but with different filenames. Allow the module to specify LOCAL_MODULE_STEM_32 and LOCAL_MODULE_STEM_64 to name the two versions. Change-Id: I573e8678c7332245a064f31246be0a05f0a9e25f

Add option for generating coverage info. 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.

Add -latomic to all target builds Projects using stdatomic.h needs libatomic.a in case compiler can't expand all __atomic* intrinsics. eg, __atomic_is_lock_free in armeabi/mips. Adding libatomic.a globally makes more sense than adding "LOCAL_LDLIB += -latomic " in each project including <stdatomic.h>. Projects don't need atomic operations won't get redundant DT_NEEDED entry because libatomic.a is not a shared library. Change-Id: I81dbf524544c848e667e18ab5eeabff75b5063ef
