Comment 3 for bug 1716203

looks like libclc -4 was used by mistake, the only diff to -3 was upload to sid.. I'll reupload a proper version. But I don't think zesty should be a concern, we don't upload mesa backports to interim releases, because usually by the time the backport hits xenial the interim release is EOL.

I'll edit the description to match what it was for 16.04.3
