OpenCV Tegra binary package - has been compiled with '--std=c++11' ?

I would like to know whetheter the pre-compiled OpenCV Tegra binary package (provided by NVIDIA, with their optimizations) is compiled with C++ 11 support enabled (gcc switch ‘–std=c++11’).
Because per default we compile all our own libraries with C++ 11 enabled (with GCC 4.8.2), and mixing libraries with C++ 11 enabled and others with C++ 11 disabled might lead to subtle bugs.
See e.g. http://stackoverflow.com/questions/9408656/do-we-need-to-recompile-libraries-with-c11
