OpenCL runtime not found

[crtrott]

Hi,

so I followed all the instructions for the X86 OpenCL runtime and it is not getting found. I also had to remove the nvidia.icd so it wouldn't pick that up.

Same system as in #646

Can I please ask you to do a few things?

1. Try running clinfo.
2. Try pointing intercept layer to /opt/intel/oclcpuexp/x64/libintelocl.so
3. Try setting export OCL_ICD_VENDORS=/etc/OpenCL/vendors (this must be a default option, but who knows)
4. Try running your SYCL app like SYCL_PI_TRACE=1 simple-sycl-app.exe

I will close this one because of ~2 months of inactivity from the reporter.

@crtrott, feel free to re-open if the problem is still exists
