* configure.in (--enable-dtrace): always call RUBY_DTRACE_BSD_BROKEN

Browse source 
for portability.
  As the note, FreeBSD 8 has DTrace as the optional
  feature (it is enabled by the build option), but doesn't have USDT.
  FreeBSD 9 has USDT but they are still optional. FreeBSD 10 will
  enable them by default.
  The variable $rb_cv_prog_dtrace_g is "yes" only on FreeBSD 9 with
  optional DTrace or FreeBSD 10. If it is "no", you cannnot know
  whether it doesn't need -G or DTrace is disabled. (by cheking
  error code, you can know)

* configure.in (--enable-dtrace): change help message
