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

[Denis Shienkov]

Hmm, how, then, about the smart *assembler* options?

For example, I have an assembler files *.s which contains both asm-code 
and c-code. It compiles before in Atmel Studio, using the "avr-gcc -x 
assembler-with-cpp" option. 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.

So, I use workaround:

cpp.assemblerName: cpp.compilerName

and pass to cpp.assemblerFlags propery the required compiler options.

I'm not sure if it is correct decision.

BR,
Denis
