在新的Android Studio NDK ninja构建系统（v 2.3+）中，转储实际的gcc/clang命令行选项的最佳方法是什么？Android Studio NDK构建忍者gcc/clang命令行选项
目前，我特意将#ERROR语句在我的C文件：
...
#include <gperf.h>
#error "Compiler, stop!"
#define LOGI(...) \
((void)__android_log_print(ANDROID_LOG_INFO, "hell-libs::", __VA_ARGS__))
所以，我可以得到下面的命令行转储：
Build hello-libs arm64-v8a
