静态库合并报错

[OuYangPaste]

描述问题

最新 dev，add_files("*.a") 链接合并所有静态库报错

错误信息

如果是xmake相关编译问题，请加上-vD参数运行，并给出完整编译输出信息以及执行的完整命令，例如：

其他信息

必须要加个.c/cpp文件 或者显式设置 add_rules("c++") 或者直接设置merge archive的rule ，xmake源码里面找下

[OuYangPaste]

xmake.lua 中增加 add_rules("c++") 或者 add_files("*.c") 后 爆以下错误:

如果直接 set_policy("build.merge_archive", true) 的话，错误信息和最开始一样

[waruqi]

这个问题 我不是群里说过了么，目前ar合并会有重名.o冲突问题，所以不建议这么干。

或者走 #1638

使用 merge_staticlib 合并测试没问题
