My use case

Using qbs and a gcc toolchain for an embedded arm
device.

I need to pass --specs=nano.specs to g++ when invoking the linker.

If I put it in cpp.linkerFlags it does not work as qbs will escape it with -Wl.

I can put it in cpp.driverFlags, but then it gets passed to every call to g++ which is useless and generates warning when using Clang Static Analyzer:

clang.exe: warning: argument unused during compilation: '–specs=nano.specs'

What to do

Add something like cpp.linkerDriverFlags with the semantics "flags to pass only when linking using the compiler binary".
