Even though unwinding depends on either HAVE_DWARF_SUPPORT or HAVE_LIBUNWIND, scripts testing unwinding can't just look for the existence of either of those flags. This is because NO_LIBDW_DWARF_UNWIND=1 can disable unwinding with libdw, but libdw will still be linked leaving HAVE_DWARF_SUPPORT turned on. Presumably because it is used for things other than unwinding, so I don't think this needs to be fixed. HAVE_DWARF_UNWIND_SUPPORT already takes the combination of all those things into account, and is used to gate the built in tests like "Test dwarf unwind", so add it to the feature list output so that it can be used by the script tests too.
