Could be false positive, but wasn't there before in catalyst 15.201

This is really a case of mixed library paths. Need to take either all crimson libraries from /usr/lib, or all from APPSDK-3.0

Mixed paths are caused by APPSDK-3.0 installation in /etc/profile.d/AMDAPPSDK.sh. This is a dangerous profile and the

LD_LIBRARY_PATH in there should be deleted.
