[boost] [sandia] Sandia-intel-16.0-c++11 is running in C++14 mode

Hi, Despite what the name implies, Sandia-intel-16.0-c++11 is actually running in C++14 mode. You can see there is -std=c++14 in the compiler command line: http://www.boost.org/development/tests/develop/developer/output/Sandia-intel... Could this inconsistency be fixed?
