When we use libmetal with other headers using stdatomic.h, we'll get symbol conflict if we don't enable HAVE_STDATOMIC_H in libmetal. The best solution might be using cmake to detect headers automatically, but we can't. Fortunately we have CONFIG_HAVE_ATOMICS macro now, which can replace HAVE_STDATOMIC_H when we're not using cmake. Note: 2-Steps to use CONFIG_HAVE_ATOMICS 1. Include compiler.h for CONFIG_HAVE_ATOMICS definition 2. Check CONFIG_HAVE_ATOMICS instead of HAVE_STDATOMIC_H Signed-off-by: Zhe Weng <wengzhe@xiaomi.com>
