Hard dependence on GLX - Githubissues

It seems that in environments where there is no GLX but qmlviewer-qt5 works all go-qml apps fail to work even if they don't import any opengl stuff. This can be tested e.g. with examples/controls/basiclayouts.

A simple way to reproduce this is to X forwarding on linux. 1) ssh -X devmachine 2) try qmlviewer-qt5 it should work 3) cd $GOPATH/src/gopkg.in/qml.v1/examples/controls/basiclayouts 4) go build 5) ./basiclayouts

Produces the following crash:

2014/11/26 09:29:33 qxcbconnection.cpp:1703: Qt: XKEYBOARD extension not present on the X server.
2014/11/26 09:29:33 qglxintegration.cpp:297: Could not initialize GLX
