Preparation for Linux 3.0

[Tetsuo Handa]

I noticed that commit 55922c9d "Linux 3.0-rc1" caused
dhcp-client 2.0pl5-19.1sarge3 (in Debian Sarge) to report SIOCSIFNETMASK and
SIOCSIFBRDADDR errors (though, it seems to me that these errors are not
affecting the functionality).

I guess this program is doing something like below.

  if grep -q ^2.6 /proc/sys/kernel/osrelease
  then
    do ioctl for 2.6 kernels
  else
    do ioctl for 2.4 kernels
  fi

We need to widely announce that userland applications using branches based on
/proc/sys/kernel/osrelease need to be fixed.
