[yocto] Yocto and Qt embedded

[Giovanni Foiani]

I solved adding in my setup-environment script all enviroment variable
related to Qt (I used paths generated by meta-toolchain-qte).

Then sourcing this environment and running into my project directory:

   - qmake2
   - make

I can successfully build Qt applications..

I still can't configure the environment to run using qt creator...
