No, it;s completely different to any BSD as the kernel is Mach based, the OS is also different in it's libs (i.e. the -framework flag).
You'd need to look in Apple's ancient fork gcc_42-5577 / llvmgcc42-2336.11 in the gcc/config/arm dir. If we targetted the later iPhone models, we wouldn't need the extra ARM instructions for the custom ARM CPU as the newer CPU's don't have custom instructions, AFAICS, just the custom hook up code for Darwin.
