[Qbs] qbs ignores the 'manual' cpp.linkerMode behavior

[Jake Petroules]

Yes, I think your solution seems reasonable. It's possible we might want a similar cpp.assemblerMode option as well, but I'm not sure.

But, in QBS it fails, because QBS launch the 'avr-as' instead of 'avr-gcc', and, seems the 'avr-as' have not similar option, so, future linking fails.
