qmake should turn off tool checking with reallyclean when using symbian-sbsv2

Because there is no targeted clean via Creator, a clean invoked with a Symbian -spec will clean all makefile targets. Under Raptor this can emit errors due to tool checks (e.g. mwccsym2 is not present).

Suggestion from the Raptor team would be to clean with "--toolcheck=off"

Errors look like this:
