Hi,
For mach-o, we encapsulate streamed IR for LTO in three special
sections with a table that describes their entries. The table is expected
to be written with native endianness for the target, but for cross-endian
cross-compilation the swapping was omitted. Fixed thus.
tested on a cross from x86_64-darwin to powerpc-darwin,
pushed to master, thanks

* simple-object-mach-o.c (simple_object_mach_o_write_segment):
Arrange to swap the LTO index tables where needed.
