Issues running Hello World openCL example missing libaltera_a10_ref_mmd.so

Hi there,

I set CL_CONFIG_CPU_EMULATE_DEVICES, and I still get the following output.

$ bin/host -emulator

Just to confirm, here is what I have CL_CONFIG_CPU_EMULATE_DEVICES set to:

$ echo $CL_CONFIG_CPU_EMULATE_DEVICES 
1 bin/host
