build with Qt4 until Qt5 is fixed to work via forwarded X11

Qt5 introduced tremendous increase in bandwidth usage for forwarded X11.
Moreover, 5.7+ segfaults, which is probably fixed in 5.9. Currently:
QT_QPA_PLATFORM=eglfs == unusable
QT_QPA_PLATFORM=minimalegl == segfauls
QT_QPA_PLATFORM=xcb QT_XCB_GL_INTEGRATION=none == nothing happens...
LIBGL_DEBUG=1 EGL_LOG_LEVEL=debug QT_LOGGING_RULES=qt.qpa.*=true
