     No, all files outside of the machine headers MUST include <machine/*.h>,
     NEVER <cpu/*.h>.

     We will either have to make stand-alone module builds use the 
     system header files in /usr/include, or we will have to construct
     a proper machine/ and cpu/ infrastructure for them just like the kernel
     and world build does.
