具体操作步骤是这样的
第一步：下载QT源码(5.12.5)，并解压
第二步：通过rsync传输目标机的sysroot
第三步：进入源码目录，配置configure文件
第四步：进入源码目录，进入qtbase目录，进入mkespcs目录，进入linux-aarch64-gnu-g++目录，修改qmake.conf：
第五步：运行脚本，然后出现提示 ’make’
第六步：编译
当qmake.conf改成下面这样的时候，configure都无法完成

用原本的qmake.conf就可以配置成功

最后编译报错：
gnu-g++ -o .obj/moc_qmlpreviewfilesystemwatcher.o .moc/moc_qmlpreviewfilesystemwatcher.cpp
