配制选项为：./configure -prefix $PWD/qtbase -xplatform linux-arm-gnueabi-g++ -opensource -no-c++11 -qreal float -nomake examples
交叉编绎之后就是没有libQt5WebKit.so.5.3.2和libQt5WebKitWidgets.so.5.3.2两个库：
用./configure -prefix $PWD/qtbase -opensource -no-c++11 -qreal float -nomake examples 命令，不指定交叉编绎会生成上面两个库
据网上资料说要编绎qtwebkit的模块的话，必须要依赖于icu库
./configure -prefix $PWD/qtbase -xplatform linux-arm-gnueabi-g++ -opensource -no-c++11 -qreal float -nomake examples -icu
error:
The ICU library support cannot be enabled.

就卡在这里了，不知道怎么回事
