问题描述：
1.编译某qt工程的32位架构二进制包时，出现了上面错误，具体错误信息如下

但是编译64位架构的rpm包时并没有报错，网上查询了标题bug相关信息，https://forum.qt.io/topic/56552/solved-pi2-qt5-4-1-std-errors-configure-errors
说是将qt从5.4.1升级到5.4.2即可解决，查看我版本机中32位mock环境的qt版本，发现已经是5.7；
想起该工程的上一次gerrit提交jenkins可以正常编译通过的，包括64位和32架构的二进制包，对比两次提交的文件差异，发现这次提交增加了两个qt相关中间文件，
| ProductLicense.pro.user.82c30c7 |
.qmake.stash
去除这两个文件后32位mock编译正常，真正原因因时间所限制，后面空了再深究。
usr/include/c++/6.4.1/bits/stl_relops.:67: Parse error at "std"
