The Product item has a "profiles" property. The envisioned use is 
something like this:
Project {
     name: "Qt"
     property string hostProfile
     property string targetProfile
}
Product {
     name: "QtBootstrap"
     profiles: [project.hostProfile]
     // ...
}
Product {
     name: "QtWidgets" // etc
     profile: [project.targetProfile]
     // ...
}
$ qbs build -f qt.qbs project.hostProfile:myHostProfile 
project.targetProfile:myTargetProfile

Our first experience with using this feature (in the Android modules) 
suggests that is probably desirable to have some sort of "sub-profiles" 
that are "aggregated" by a parent profile. (This sounds blurry, because 
it is.)
