There's no way :-(

Of course, it's not that bad. One can start by inlining toolset.inherit call: 

import gcc ;

inherit-generators darwin : gcc ;
inherit-flags darwin : gcc ;
inherit-rules darwin : gcc ;

And then modify inherit-flags by adding a third parameter. That parameter 
would be a list of properties flags settings for which should not be 
inherited. Inside the body of inherit-flags, you would add

if [ set.intersection $(.$(rule-or-module).condition.$(f)) :
$(prohibited-properties ] 

before adding the flag in new module. Care to try this idea ;-)
