It's a reasonable thing to do.  The disease in this case is that the
absolute input section isn't attached to each bfd that defines absolute
symbols.  However, fixing that properly requires quite a large patch.

I'm committing a more direct approach than your patch.  There are other
sections besides the absolute section that won't have coff_section_data.

	* coffgen.c (bfd_coff_get_comdat_section): Check that
	coff_section_data isn't NULL.
