I have spun a new patch for the additional Build-Depends: and will
submit it once testing is complete.

>From an SRU testing standpoint the application of this patch is benign
so if we do not have a respin (when we should consider including this
additional patch) we can consider this "verification-done" for the
purposes of letting this bit of the fix out.  We can then reopen the bug
for the next piece.

Bug description:
  Hi,

  I'm trying to use perf's libunwind support in 13.04 with kernel
  3.11.0-12-generic on amd64.  Typically you can do this by using the
  "-g dwarf" flag, but it appears the perf command included in linux-
  tools-3.11.0-12-generic was not compiled with libunwind.  This may be
  as simple as the build machine didn't have libunwind installed.
  Having dwarf support in perf with default Ubuntu kernels would be very
  useful as it provides a way to get profiling information when
  -fomitframepointer is used.

  Relevant upstream code:

  https://github.com/torvalds/linux/blob/v3.11/tools/perf/Makefile#L459
  https://github.com/torvalds/linux/blob/v3.11/tools/perf/builtin-record.c#L758

  Let me know if I can provide any other information.
