当前8.26 openEule 门禁和构建工程中gcc存在问题，并非dtc自身源码导致的编译报错
unresolvable: have choice for libstdc++.so.6()(64bit) needed by gcc: gcc-toolset-12-libstdc++ libstdc++

8.25日 https://build.openeuler.openatom.cn/build/openEuler:23.09/standard_x86_64/x86_64/dtc/_log中上述gcc语句突然中断。但本地可以构建成功，建议等待构建环境gcc正常后再进行构建。

8.28 构建环境gcc正常后，dtc构建依然失败，正在定位失败原因，gcc升级到gcc12 新增编译选项导致告警出现，-werror将报警转换为error导致编译构建失败。如下为统一文件编译选项差异。
