Thanks, fixed.

Done. Other options report instruction sets, so i left them.
OK for trunk?
2013-12-19 Tocar Ilya <ilya.to...@intel.com>
* config.gcc: Support march=broadwell.
* config/i386/driver-i386.c (host_detect_local_cpu): Detect Broadwell.
* config/i386/i386.c (ix86_option_override_internal): Add broadwell.
* doc/invoke.texi: Document march=broadwell.
