obj some_source : some_source.cpp ;
obj some_source : some_source.cpp : <toolset>gcc-4.6.0 : <cxxflags>-std=c++0x ;
obj some_source : some_source.cpp : <toolset>gcc-4.5.2 : <cxxflags>-std=c++0x ;

You could also do it all in a rule like:

rule some_source_requirements ( properties * )
{
   if gcc-4.6.0 gcc-4.5.2 in $(properties:G=)  { return <cxxflags>-std=c++0x ; }
}

obj some_source : some_source.cpp : <conditional>@some_source_requirements ;
