Since you're specifically interested in OS X, I'd follow this advice,  
and then look at /usr/include/mach-o/getsect.h. This header declares a  

extern char *getsectdata(
     const char *segname,
     const char *sectname,
     unsigned long *size);

which seems like it'll give you all of the data in one of the sections  
of the executable file for the currently running program. I haven't  
used it, though, so I'm not positive about how it works.

I think it's then fairly straightforward to tell the linker to just  
include an arbitrary file into a section with a name of your choice.
