[Qt-creator] Very slow GDB when stepping into functions

[Peter Kümmel]

Maybe someone also wonders why stepping into a function
takes several tens of seconds at 100% CPU usage of gdb.
Here's the answer for Debian based systems: 

"Debugging symbols for ld.so are not shipped"

Therefore this:
   sudo apt-get install libc6-dbg
solves the problems on my Ubuntu machine.

Could someone please update the QtCreator Wiki:
