Doing something along the lines of

./linuxdeployqt-continuous-x86_64.AppImage appdir/usr/share/applications/*.desktop -bundle-non-qt-libs
mkdir -p appdir/usr/optional/ ; wget -c https://github.com/darealshinji/AppImageKit-checkrt/releases/download/continuous/exec-x86_64.so -O ./appdir/usr/optional/exec.so
mkdir -p appdir/usr/optional/libstdc++/ ; cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 ./appdir/usr/optional/libstdc++/
( cd appdir ; rm AppRun ; wget -c https://github.com/darealshinji/AppImageKit-checkrt/releases/download/continuous/AppRun-patched-x86_64 -O AppRun ; chmod a+x AppRun)
./linuxdeployqt-continuous-x86_64.AppImage appdir/usr/share/applications/*.desktop -appimage

should resolve this.
