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 -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

Don't add dependencies on Makefiles when using ninja Ninja has an implicit dependency on the command being run, and kati will regenerate the ninja manifest if any read makefile changes, so there is no need to have dependencies on makefiles. This won't catch all the cases where LOCAL_ADDITIONAL_DEPENDENCIES contains a .mk file, because a few users of LOCAL_ADDITIONAL_DEPENDENCIES don't include base_rules.mk, but it will fix the most common ones.
