      Bug #47391 no stack trace printed to error log on 
      solaris after a crash
      
      This patch adds a Solaris-specific version of
      print_stacktrace() which uses printstack(2). The symbol
      names are mangled, so use of c++filt may be required as
      described in the MySQL documentation.
