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.
