Re: some more warning fixes

[Alan Modra <amodra at bigpond dot net dot au>]

I missed this one from the last commit.

	* mach-o.c (bfd_mach_o_scan): Don't ignore return value of
	bfd_mach_o_scan_start_address.

To compile the 32-bit elfxx-ia64.c target on a 32-bit host, ie. when
bfd_vma is 32-bit requires a rewrite of elfNN_ia64_relax_brl.  Or at
least use of long long vars instead of bfd_vma.  I chose to rewrite.

	* elfxx-ia64.c (elfNN_ia64_relax_brl): Rewrite for 32-bit bfd_vma.
	(elfNN_ia64_relax_section): Use ELFNN_R_INFO, not ELF64_R_INFO.

sort_dynamic_relocs_64 uses ELF64_R_SYM, and 64-bit bfd operations can't
work when bfd_vma is 32-bit.

	* elfxx-mips.c: Remove unnecessary prototypes.
	(sort_dynamic_relocs_64): Abort if not BFD64.
