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 "
...
