I didn't know off hand either,
but found this in automake/m4/missing.m4:

  # AM_MISSING_HAS_RUN
  # ------------------
  # Define MISSING if not defined so far and test if it supports --run.
  # If it does, set am_missing_run to use it, otherwise, to nothing.
  AC_DEFUN([AM_MISSING_HAS_RUN],
  [test x"${MISSING+set}" = xset ||
    MISSING="\${SHELL} `CDPATH=:; cd $ac_aux_dir && pwd`/missing"
  # Use eval to expand $SHELL
  if eval "$MISSING --run :"; then
    am_missing_run="$MISSING --run "
  ...
