The system isn't designed for this. toolset.flags only
allows options to be added. They can't be removed.
It is possible to fix the flags manually, but it's
rule compile.c++ ( targets * : sources * : properties * )
C++FLAGS on $(targets) = [ set.difference
[ on $(targets) return $(C++FLAGS) ] :
/EHs ] ;
