Describe the bug

用Qt6无法编译测试程序qt.console

Expected behavior

正常编译

Error output

...
error: main.cpp
C:\Qt\6.0.0\msvc2019_64\include\QtCore/qglobal.h(379): error C7525: inline variables require at least '/std:c++17'
...

Related Environment

Please provide compiling and running environment information:

• xmake version: 2.3.9
• os: Windows 10
• target platform: windows

Additional context

Qt6使用C++17，因此必须要用C++17的flag编译，而自动生成的测试程序使用的是C++11

qt6我没特别测过，应该需要做些适配调整才行，不过最近2.5.1开始收尾了，除非特别严重的问题或者不会花费太多时间就能解决的小问题

其他的都统一放到2.5.2处理

可以了，dev上
