fatal error: gnu/stubs-soft.h: No such file or directory

我已经完成了Qt源码的交叉编译，但在用Qt Creator构建时，出现了如下错误：

致命错误是没有stubs-soft.h文件，我检查了我当前系统中的报错路径下的文件，的确是没有，有的是stubs-hard.h。
虽然我明白这是根据宏定义来实现选择：

#if !defined __ARM_PCS_VFP
# include <gnu/stubs-soft.h>
#endif
#if defined __ARM_PCS_VFP
# include <gnu/stubs-hard.h>
#endif

复制代码

并且，我查阅了大量资料，说是在toolchain.cmake和qmake.conf中对编译器标志添加-march=armv7-a -marm -mfpu=vfp -mfloat-abi=hard，我的确是这么做了，并且变体这两个文件很多次，可始终都会报错。我不清楚是不是我的这两个文件哪里有问题，所以我贴在那里，希望有大佬能指点一下：

我不清楚的是，明明我没有设置-mfloat-abi=softfp，为什么在构建的报错信息中仍旧存在使用软浮点的选项

已解决该问题。需要更改qmake.conf
