All OpenCL ICDs with shared LLVM are useless if they can't be used
in real programs, so my opinion for whats its worth is that they link
statically with LLVM until the issue is resolved in another way allowing
shared LLVM (probably Stretch+1 material).
Of course this is just my opinion

Statically linking to LLVM (see attached) fixes this bug, but I'm not
sure yet whether we want to do that.

This bug goes away on rebuilding beignet with LLVM 3.8 (but that isn't a
good solution as it can trigger #848368, and also disables some of
beignet's functionality).
Debug backtraces show mesa-opencl-icd being loaded first, and the crash
happening when beignet-opencl-icd is loaded, suggesting
Control: retitle -1 beignet+mesa-opencl-icd crash if installed together
The lack of hardware isn't the trigger - having beignet-opencl-icd and
mesa-opencl-icd installed at the same time is. (beignet+pocl or
mesa+pocl is OK.)
Looks like some kind of "seeing the other ICD's copy of libllvm ins
