[RFA] New port: CR16: BFD Changes required by the gdb port

[Kaushik Phatak]

Hi Nick,
Thanks for applying these changes with appropriate Changelogs.

I noticed that the entries for cr16 were missing in the latest gdb snapshot
in configure.ac and configure.

  cr16-*-*)
    noconfigdirs="$noconfigdirs gdb"
    ;;
This entry is present in the 7.5 release version of gdb but not
in the latest snapshot, gdb-7.5.50.20130108

How is this controlled, in gcc or here? Could you please throw some light on this.

Please let me know if I need to submit any patch for this as couple of hunks
from my gdb patch are failing due to this.

Thanks,
Kaushik
