  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=44254

  Log:
    configure.in: build probes with systemtap's dtrace wrapper
    
    * configure.in (RUBY_DTRACE_POSTPROCESS): Fix compatibility with
      systemtap on linux. stap requires `dtrace -G` post-processing, but
      the dtrace compatibility wrapper is very strict about probes.d
      syntax.
