** Description changed:

+ [Impact]
+ iscsitarget-dkms will fail to build for 4.4.0 kernels on trusty, when their 
ABI start with 1, like in -100 or -101.
+ 
+ [Test Case]
+ Install different kernels, including 3.13, and 4.4, and 4.4.0-78, 4.4.0-81 
and 4.4.0-101. That means different kernel base versions, different ABIs, 
including the offending one (that starts with 1), and the one that had not have 
the sock_recvmsg signature changed. All build successfully.
+ 
+ [Regression Potential]
+ Builds could fail with a future kernel or an old kernel we haven't tested 
with. A similar solution has already been applied to xenial. Some other way of 
calling dkms could make the build fail. Different ways have been tested in this 
case.
