  Let Asterisk find better backtrace information with libbfd.
  
  The menuselect option BETTER_BACKTRACES, if enabled, will use libbfd to search
  for better symbol information within both the Asterisk binary, as well as
  loaded modules, to assist when using inline backtraces to track down problems.
