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
