#|Description:  This shell script used download and compile QT5 for ARM
#|     Author:  GuoWenxue <guowenxue@gmail.com>
#|
#|   WARNNING:  QT >= 5.7 need crosstool g++ support C++11 support
#|              QT configure need host g++ support C++11, so need config g++ on ubuntu host:
#|              sudo update-alternatives --config g++
#|
#|  ChangeLog:
#|           1, Initialize 1.0.0 on 2011.04.12
