--- Comment #14 from Iain Sandoe <iains at gcc dot gnu.org> 2011-03-13 20:54:03 UTC --- (In reply to comment #13) > Alright, multiple segments will not work.

Segments aren't really used in mach-o object files. All mach-o object files have exactly one LC_SEGMENT load command. It is final linked images that support multiple LC_SEGMENT load commands. It is possible to fix this in Xcode 4.x, but I think a solution that just uses one section for all gcc LTO data (and have your own sub-section scheme) will work with all darwin assembler versions." == I can only hope that the simple_object interface in libiberty will make this possible without introducing a dependency on libelf (which seems a little OTT for this relatively small requirement).
