I have not done this, but Darwin's binary format is Mach-O (as opposed
to ELF for most modern non-Mach Unixes), which has built-in support for
fat executables and libraries.  The OpenDarwin 7.2.1 install CDs
(corresponds to Mac OS X 10.3.2) lay down pretty much all the userland
as fat objects.  You could probably learn a lot from the project's build
scripts, check out http://darwinsource.opendarwin.org/10.3.2/ and
http://opendarwin.org/projects/darwinbuild/

Note that the latest official release, OpenDarwin 8.0.1 (basis of Mac OS
X Tiger), appears to be released as two separate CDs for the two
platforms, so its build scripts may have removed fat support.
