Hi Olaf \ Suzuki \ Jörn,

Thanks for all your response. Below are our observations with respect to
Ubuntu 16.04(x64), 16.10(x64), 17.10(x86) & 17.10(x64). Also mentioned are

What I understand from your earlier notes, there has been some changes in
the way how Debian based distributions arrange their libraries to add
support. So does this simply mean we need to handle it out from our scan
