** Description changed:

  With bug #1403511 taken care of in Qt, apps do not anymore crash with Qt
  5.4 and device does not anymore go into reboot loop. However, nothing is
  visible on the screen.
  
  It seems unity8, unity8-dash etc are all running. unity8.log attached
+ 
+ 05/2015 status:
+ - We require at least -fPIE on arm for QObject::connect to work, but on the 
other hand -fPIC armhf is broken like described in this bug
+ - Upstream is moving to require -fPIC while banning -fPIE, which means we 
should move to -fPIC too and use -reduce-relocations (requires -fPIC from now 
on) on all archs
+ 
+ Relevant upstream links referring GCC5 as the reason to require -fPIC:
