PATCH: Prevent h8300 targeted gas from aborting on .quad pseudo-ops

[Nick Clifton]

Hi Guys,

  The h8300 port of gas can run into an abort if it is asked to apply
  a fixup for an 8-byte value.  eg:

  	.section .debug_line
	.4byte		0xffffffff
	.quad		bar - foo
       foo:
       bar:

  I am applying the patch below so that an error message is generated
  instead.

Cheers
  Nick
