git clone https://gitorious.org/qt/qt5.git
cd qt5
./init-repository

Create qtbase/mkspecs/linux-arm-gnueabihf-g++ directory; copy files from qtbaase/mkspecs/linux-arm-gnueabi-g++/*; and then edit qmake.conf for tool names.

./configure -xplatform linux-arm-gnueabihf-g++ -opensource -confirm-license -optimized-qmake -reduce-exports -release -qt-xcb -nomake tests -prefix /opt/local/arm-linux-gnueabihf/usr/local/qt5 -no-pch

make -j4

This end up with an error: x11 development package not found while building WebKit.  I've tried -no-webkit for configuration option but configure return unknown option error for it.  According to following post:

https://forum.qt.io/topic/22960/solved-lubuntu-12-10-package-x11-not-found-qt5

I've commented out PKG_CONFIG += x11 lines from three qmake files, and then went through make process and built them all.
