Comment 7 for bug 1195607

I'm seeing the problem today on a new install I'm setting up of 3.11.0-19-generic:

...
make KERNELRELEASE=3.11.0-19-generic -C /lib/modules/3.11.0-19-generic/build M=/var/lib/dkms/iscsitarget/1.4.20.2/build....(bad exit status: 2)
Error! Bad return status for module build on kernel: 3.11.0-19-generic (x86_64)
Consult /var/lib/dkms/iscsitarget/1.4.20.2/build/make.log for more information.
