Bug description:
  It looks like 12.04.2 uses kernel 3.5 line although `linux-tools-
  common` depends on kernel 3.2 line. In order to use `perf` tool it is
  always required to install the correct version manually which is
  broken when kernel updates.

  Steps to produce:

  1. Use a fresh 12.04.2 install
  2. Install linux-tools-common

      $ sudo apt-get install linux-tools-common
      ..

  3. Try to run perf tool and get the error:

      $ perf stat /bin/ls
      perf not found for kernel 3.5.0-44
      You may need to install linux-tools-3.5.0-44-generic

  (Optional workaround)

  4. Install the correct version manually:

      $ sudo apt-get install linux-tools-3.5.0-44
      ..
      $ perf stat /bin/ls
      .. (runs as expected)

  5. Update to the next kernel version when an update comes in
  6. Now the perf tool stops working and needs your attention to manually update to the next version:

      $ perf stat /bin/ls
      perf not found for kernel 3.5.0-45
      You may need to install linux-tools-3.5.0-45-generic

  7. Rinse and repeat
