C++ build errors with some intel compilers

[matthewhoffman]

From @xylar:
I'm seeing build errors when I try to build MALI (without Albany) on Compy with intel and impi (the compass default settings from MPAS-Dev/compass#126):
In file included from Interface_velocity_solver.cpp(19):

I was able to build on Compy by adding -std=c++11 to the CXXFLAGS_OPT :
CXXFLAGS_OPT = -O3 -std=c++11
