When I run clinfo to see what is available, I got "Invalid instruction" signal and core dump. Should I file the bug? Can beignet run on non-Intel CPU?

For me, this seems a beignet bug: the ICD should report no plateform
if no useful harware is found. It should not crash.

That said, I've several remarks:
* ocl-icd-libopencl1 has some bugs in the 1.3-3 version when
  detecting platforms with ICDs that reports no plateform
  => if you are using ocl-icd-libopencl1 as ICD loader, try
  2.0.2-1 version from experimental
* I suppose that this is beignet that provides libocl.so.0 and
  that this is the presence of this library that trigger the bug
* if beignet installs libocl.so.0, I think that beignet developers
  should choose another name for there ICD shared library. ocl is
  way too generic for an OpenCL library...
