Build for Sandybridge and Haswell

I work on a Cray HPC.  The login nodes are Intel Sandybridge and the compute nodes are Intel Haswell.  We need our software system to be optimized for both Intel architectures.  I am compiling our libraries and executables with -axCORE-AVX2,AVX as instructed here:

However, when I run an executable on the login node (i.e. Sandybridge), I get the following runtime error:

Please verify that both the operating system and the processor support Intel(R) MOVBE, FMA, BMI, LZCNT and AVX2 instructions.

Any help is greatly appreciated.
