MKL HPCG Benchmark -- Missing MKL support and Incorrect Usage

I downloaded the MKL Benchmark set (for Linux) today, from:

  https://software.intel.com/en-us/articles/intel-mkl-benchmarks-suite

But the HPCG benchmark I wanted to run doesn't appear to actually support MKL -- the printed usage options list:

--mkl=yes/no: use MKL (default no)

but this doesn't appear to be implemented in the code, and trying to use it with the binaries gives:

$ ./xhpcg_avx --mkl=yes
./xhpcg_avx: unrecognized option '--mkl=yes'
$ ./xhpcg_avx --mkl yes
./xhpcg_avx: unrecognized option '--mkl'

Has anyone heard anything about whether this is going to be implemented? It seems odd to have it listed in a released download but still returning an error.
