[Qt-interest] line number '0' for Qt libs under Qt Creator'sdebugger

[Garth Dahlstrom]

Thanks Scott!

I rebuilt with -debug in the config and now I get line numbers during  
the callbacks.

This was my config line for static + debug on Windows:
    configure -opensource -static -debug -fast -no-dsp -no-vcproj -no- 
phonon-backend -no-dsp -no-vcproj -no-incredibuild-xge -no-plugin- 
manifests -no-exceptions
I also deleted everything after "first:" in examples/Makefile and  
demos/Makefile (to keep from building examples and demos) and then ran  
make to build everything else.

Guess the shipped binaries would have debug symbols stripped out to  
save space?  Good to know.

Cheers,

-G
