如何解决QT移植3516D，./configure出现重复定义问题

今天想把QT移植到dv300，今天在网上找教程，找到这位大神的移植教程

我的ubuntu12.04，我按照他的步骤，下载了qt-everywhere-src-5.12.0.tar.xz到./configure -prefix /opt/qt5.12.8_hi3516dv300/shared的时候就出现了错误，如下：

.In file included from /home/phoenix/OPT/qt-everywhere-src-5.12.0/qtbase/include/QtCore/qendian.h:1:0,

似乎是似乎是个和大小端有关的函数，出现qbswap重复定义的错误了，有没有大佬遇过相似的问题?
