Since it must keep the same timestamps on config.status and Makefile, I used

if touch --reference=config.status config.status.tmp > /dev/null 2>&1; then
  sed '/as_fn_exit 0/i \
sed -e \"s/^\t\\\(\\\$(AM_V_CCLD)\\\)/\t+ \\\1/\" Makefile > Makefile.tmp \
touch --reference=Makefile Makefile.tmp \

If touch doesn't support --reference, the workaround isn't applied.
