 All the uses of <sys/systm.h> appear to be to get the SCARG macro.  As a
 fix, do we find another header for this macro?  <sys/syscallargs.h> seems
 best at a quick glance, except that it's autogenerated.  It wouldn't be
 too hard to get makesyscalls.sh to add these macros at the bottom of the
 header.
