Bug description:
  SRU Justification:

  [Impact]
  Users of ppc64el hardware need the ability to use crashdumps to do kernel debugging.

  [Test Case]
  1) apt-get install kdump-tools
  2) kdump-config load
  3) this should pass but fails because it expects vmlinuz

  [Regression Potential]
  This fix allows the existing case to work, but only checks for vmlinux if vmlinuz is missing.

  --

  On ppc64el, there's no vmlinu/z/, only vmlinu/x/.

  Thus, kdump-config load fails as follows:

  # kdump-config load
  Cannot open `/boot/vmlinuz-3.13.0-27-generic': No such file or directory
   * failed to load kdump kernel

  This small patch (attached) fixes the issue.
  It defaults KDUMP_KERNEL to vmlinux if vmlinuz is not found.

  # cd /usr/sbin && patch -p1 < ~/kdump-config-vmlinux.patch
  patching file kdump-config

  # kdump-config load
  [...]
   * loaded kdump kernel
