Ah, so its not about targets, but rather about passing make variables
into the make invocation. That indeed makes even more sense to add, but
should probably be something like a QMap and the make-builder will then
take care of creating the correct commandline. So something like

build( target )
build( target, variables )
build( targetlist )
build( targetlist, variables )

as API, where the single-target function would just be convenience API
calling the list-version with a single-item-list...
