Jin Yao 5008c125d5 perf report: Fix no libunwind compiled warning break s390 issue 
[ Upstream commit c3314a74f86dc00827e0945c8e5039fc3aebaa3c ]

Commit 800d3f561659 ("perf report: Add warning when libunwind not
compiled in") breaks the s390 platform. S390 uses libdw-dwarf-unwind for
call chain unwinding and had no support for libunwind.

So the warning "Please install libunwind development packages during the
perf build." caused the confusion even if the call-graph is displayed
correctly.

This patch adds checking for HAVE_DWARF_SUPPORT, which is set when
libdw-dwarf-unwind is compiled in.

Fixes: 800d3f561659 ("perf report: Add warning when libunwind not compiled in")
