[Patch mach-o] correct some section specification nits.

[Iain Sandoe]

A few nits (although the wrong alignment value for eh-frame does break  
cfi_directives...)

OK?

bfd:

	* mach-o.c (mach_o_section_name_xlat): Correct eh-frame section
	parmaters.
	* mach-o-x86-64.c (text_section_names_xlat): New.
	(mach_o_x86_64_segsec_names_xlat): New.
	(bfd_mach_o_tgt_seg_table): Define to mach_o_x86_64_segsec_names_xlat.
	* mach-o-i386.c (text_section_names_xlat): Correct section parameters.
