qbs only look at direct dependicies when choosing gcc or g++ linker

Here is simplified example. (I use gcc toolchain, bur problem is )

I have `my_c_static` - statically compiled c-library, 'my_cpp_static' - staticaly compiled cpp library and `my_dynamic` - dynamicaly linked library.

Error occures when 'my_c_static' depends on 'my_cpp_static', and 'my_dynamic' depends on 'my_c_static', is this case qbs looking through all inputs, finding no `cpp_obj` or `cpp_staticlibrary` chooses gcc as linker, what results is linker errors because there is cpp library that is being linked to this binary.

If i directly(or via export in `my_c_static`) make a dependency from `my_dynamic` to `my_cpp_static`, g++  is chosen correctly and project compiles
