[Patch libiberty/mach-o] fix byte-swapping of indices in wrapper sections.

[Iain Sandoe]

Found while testing x86 X ppc ...
.. I missed byte-swapping the indices when outputting the index of the  
GNU wrapper for LTO sections.
OK/When?

        * simple-object-mach-o.c (simple_object_mach_o_write_segment):
        Byte-swap indices when required.
