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

[timur.kristof at gmail.com]

Hi Denis,

This issue has been asked several times.
The short answer is this: put the real linker flags without -Wl into
linkerFlags and put the other ones into driverFlags.

linkerName and linkerMode are uneeded (as far as I know).

Here is an example of how I did it:

rts/ArmMcuProduct.qbs



Hope this helps,
Timur
