Define __EH_FRAME_BEGIN__ etc for arm-coff

[Nick Clifton]

Hi Guys,

  I am checking in the following patch to define __EH_FRAME_BEGIN__
  and __EH_FRAME_END__ for the arm-coff port.

Cheers
        Nick

        * scripttempl/armcoff.sc: Define __EH_FRAME_BEGIN__ and
        __EH_FRAME_END__ and accept eh frames into data section.
        Add ctor and dtor sections.
