Unfortunately there's no single switch for that. You can however modify 
your Qt profile like this:

Note the profile you're currently using, or use "qbs config 
defaultProfile" to find out what the default profile is.

Find the profile's search path:

$ qbs config --list profiles.qt562.preferences
profiles.qt562.preferences.qbsSearchPaths: 
"/home/someone/.config/QtProject/qbs/1.9.0/profiles/qt562"

Replace cpp.includePaths with cpp.systemIncludePaths in the Qt modules 
of that profile:

$ find 
/home/someone/.config/QtProject/qbs/1.9.0/profiles/qt562/modules/Qt/ 
-name '*.qbs' | xargs -n1 sed -i s/cpp\.includePaths/cpp.systemIncludePaths/

Afterwards, all Qt include paths for this profile are passed via 
-isystem to the compiler.
