Looks like they try to use 'tail' to skip over something, but the + sign
in your uname -r gives it indigestion.  Try building with a version name
that doesn't include a + sign, and complain to the maintainers of mkknlimg
that they've probably got a parameter quoting problem (most likely, there's
someplace a

tail -this -that $foo

needs to be

tail -this -that "$foo"
