Try the script below instead, it might not fix everything, but it's less 
hit-and-miss than manually searching for a configuration backup that you 
may not even have.

#!/bin/bash
if [ -h /usr/src/linux ]; then
  echo 'You have a /usr/src/linux symlink, good.'
  if [ "$(readlink /usr/src/linux)" == "linux-$(uname -r)" ]; then
     echo 'It points to your running kernel, also good.'
  else
     echo "But, it points to the wrong place.  I'll fix it."
     ln -snf "linux-$(uname -r)" /usr/src/linux || exit 127
  fi
elif [ -e /usr/src/linux ]; then
  echo 'You have a /usr/src/linux, but it is not a symlink.'
  echo "Your system is broken, but I can't automatically fix it."
  exit 1
else
  echo "You don't have a /usr/src/linux, let me make one for you."
  ln -snf "linux-$(uname -r)" /usr/src/linux || exit 127
fi

if [ -r /proc/config.gz ]; then
  echo 'You have a /proc/config.gz, good.'
else
  echo "You either don't have a /proc/config.gz or I can't read it."
  echo "Sorry, I can't access the configuration of your running kernel."
  exit 1
fi

if [ -r /usr/src/linux/.config ]; then
  echo 'You already have a readable /usr/src/linux/.config, hrm.'
elif [ -e /usr/src/linux/.config ]; then
  echo "Your /usr/src/linux/.config exists, but I can't read it."
  echo "There's probably a permissions problem somewhere."
  exit 1
else
  echo 'No /usr/src/linux/.config, using running config.'
  zcat /proc/config.gz > /usr/src/linux/.config || exit 127
  exit 0
fi

if zcat /proc/config.gz | diff /usr/src/linux/.config - ; then
  echo 'Your /usr/src/linux/.config and your running configuration agree.'
  echo "I can't believe you wasted my CPU cycles. ;)"
  exit 0
else
  echo -n 'Your /usr/src/linux/.config and your running configuration '
  echo -n 'are different.  You should build and install, as needed, this '
  echo -n 'new configuration.  After doing so, you should be able to '
  echo -n 'compile out-of-tree modules, but they will not be usable until '
  echo    'you boot into the newly configured kernel.'
  exit 1
fi
