[Boost-testing] [boost][testing] difference between using 'toolset' as an option to run.py and bjam_options

While running regression tests, I see one can provide 'toolset' option 
as follows:

python run.py --toolset=sun ... "--bjam-options=-j8 toolset=sun 
stdlib=gnu cxxflags=\"-std=c++11\" linkflags=\"-std=c++11\" " ...

I am assuming the first 'toolset' option is to build the testing tools, 
whereas the second 'toolset' passed on to --bjam-options is for running 
the regression tests themselves.

When compiling with -std=c++11,
my  tools/build/src/tools/sun.jam file contains,

       42 feature.extend stdlib : gnu ;
      43 feature.compose <stdlib>gnu
      44     : <cxxflags>-std=c++03 <linkflags>-std=c++03
      45     ;
      46

so the above  'python run.py ...' command works well.

Now, if I add the following lines to sun.jam,

      47 feature.extend stdlib : gnu_cxx11 ;
      48 feature.compose <stdlib>gnu_cxx11
      49     : <cxxflags>-std=c++11 <linkflags>-std=c++11 
<linkflags>-library=stdcpp,CrunG3
      50     ;

and run the regression tests as follows:
python run.py --toolset=sun ... "--bjam-options=-j8 toolset=sun' 
stdlib=gnu_cxx11 ...

My test run fails as follows:
notice: [python-cfg]   library path: "/usr/lib/python2.7/config" "/usr/lib"

scope from module

Is there something else I need to do at my end to get this to work if I 
modify sun.jam as above?

Thanks,
