Fix compile time warning in bfd/coffcode.h

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix a compile time warning building
  bfd/coff64-rs6000.c, although the actual problem was in coffcode.h.
  The coff64-rs6000.c defines its own swap table, so the default
  coff_std_swap_table structure defined in coffcode.h is not used.

Cheers
  Nick

	* coffcode.h (coff_std_swap_table): Add an unused attribute in
	case it is not used.
