Drop darwin-user
It's been orphaned, not compiling for a long time and despite Apple's drop of their Rosetta ppc emulation technology with Mac OS X Lion no one has stepped up to fix it. Testing necessary changes wrt QOM'ification thus is impossible, so we might as well remove it completely.

-In order to launch a Mac OS X/Darwin process, QEMU needs the process executable

-CD or compile them by hand.
-

-
-@item On x86, you can just try to launch any process by using the native
-libraries:
-
-@example
-qemu-i386 /bin/ls
-@end example
-
-or to run the ppc version of the executable:
-
-@example
-qemu-ppc /bin/ls
-@end example
-
-@item On ppc, you'll have to tell qemu where your x86 libraries (and dynamic linker)
-are installed:
-
-@example
-qemu-i386 -L /opt/x86_root/ /bin/ls
-@end example
