mkdir sub1 sub2
cat >configure.ac <<EOF
AC_INIT([t-parallel], 1, [devnull])
AM_INIT_AUTOMAKE([foreign])
AC_CONFIG_FILES([Makefile sub1/Makefile sub2/Makefile])
AC_OUTPUT

echo 'SUBDIRS = sub1 sub2' >Makefile.am
cat >sub1/Makefile.am <<EOF
all:
        sleep 3
        echo sub1 done
EOF
cat >sub2/Makefile.am <<EOF
