perf: parse the .debug_frame section in case .eh_frame is not present
On ARM the debug info is not present in the .eh_frame sections but
in .debug_frame instead, in dwarf format.
Use libunwind to load and parse the debug info.
Dependencies:
. if present, libunwind >= 1.1 is needed to prevent a segfault when
parsing the dwarf info,
. libunwind needs to be configured with --enable-debug-frame. Note:
--enable-debug-frame is automatically selected on ARM.
