[PATCH 1/1] perf debuginfo: Fix the build with !HAVE_DWARF_SUPPORT

[Arnaldo Carvalho de Melo <acme@kernel.org>]

In that case we have a set of placeholder functions, one of them uses a
'Dwarf_Addr' type that is not present as it is defined in the missing
DWARF libraries, so provide a placeholder typedef for that as well.

The build error before this patch, a static build out of 'make -C tools/perf build-test':

  In file included from util/annotate.c:28:
  util/debuginfo.h:44:46: error: unknown type name ‘Dwarf_Addr’
