Use the Xcode gui to find the correct compile options for the sort of kext you are developing, and then create a makefile based on that. When upgrading Xcode, and/or major OS versions, it is generally a good idea to re-check that your compiler and linker flags are correct. I sometimes (well, almost always) forget to do this.
