Not with the standard tools. 

A Qt release build builds with -g1 instead of -g, which should be sufficient 
for backtraces but not for debugging.

But you can't strip the info once created. So you will have big debug symbols 
if you build with either -debug or with -release -force-debug-info.

You need a specialised stripper tool. I remember some colleagues had proposed 
to do that for Clear Linux, but I don't know if they actually accomplished it. 
I can ask in the new year, if you remind me.
