Subject: [PATCH v2 10/31] perf build: Rename HAVE_DWARF_SUPPORT to HAVE_LIBDW_SUPPORT

In Makefile.config for unwinding the name dwarf implies either
libunwind or libdw. Make it clearer that HAVE_DWARF_SUPPORT is really
just defined when libdw is present by renaming to HAVE_LIBDW_SUPPORT.

Signed-off-by: Ian Rogers <irogers@...gle.com>
