Sketcher: Workaround for Eigen bug: SparseQR crash on matrices with rows>cols

Browse Source 
=============================================================================

There is an issue with an assertion in Eigen, as reported here:
https://forum.kde.org/viewtopic.php?f=74&t=117474
http://forum.freecadweb.org/viewtopic.php?f=10&t=11341&p=92153#p92146

The work-around is to disable debug assertions for Eigen until the problem
gets solved.
