cc1: all warnings being treated as errors

tools/make/targets.mk:26: recipe for target 'position_controller_indi.o' failed

make[1]: *** [position_controller_indi.o] Error 1

make[1]: *** Waiting for unfinished jobs....

Makefile:375: recipe for target 'build' failed

make: *** [build] Error 2

原因：
出现这样的提示 cc1plus: all warnings being treated as errors，原因是编译时候gcc配置把警告按错误处理
 
解决：
在Makefile中找到 -Werror项，删除即可。删除后重新编译。
