【背景】
当前仓代码存在编译告警需要处理

【修改方案】
在测试用例中屏蔽了-Werror选项
在对应的代码处添加了相应函数的声明头文件

【影响】
对现有的产品编译不会有影响。

Merge pull request !527 from JerryH/iar_thread_local

在需要IAR的thread_local特性时，在targets_config.h中包含los_iar_tls.h，覆盖los_config.h的默认定义，使能该特性。

Merge pull request !528 from SimonLi/master

背景：
1. //kernel/liteos_m/BUILD.gn通过excutable生成config.gni文件到
out目录下
2. //kernel/liteos_m/liteos.gni定义内核模板，依赖out目录下的config.gni
意味着使用内核模板的模块（例如device/board、device/soc）需要依赖
kernel/liteos_m/BUILD.gn先加载，有这个顺序依赖约束。

解决方案：
将生成config.gni部分移到liteos.gni模块定义处，解决这个约束。
