Thanks.

I've pushed the patch below.
When I run "make sc_prohibit_AC_LIBOBJ_in_m4",
it complains about the following:
m4/fprintftime.m4: AC_LIBOBJ([fprintftime])
m4/printf-posix-rpl.m4: AC_LIBOBJ([printf])
m4/stdio-safer.m4: AC_LIBOBJ([tmpfile-safer])
Do not use AC_LIBOBJ in m4/*.m4;
see <http://article.gmane.org/gmane.comp.lib.gnulib.bugs/26995>
Did you deliberately omit those three from the list of modules
that should be exempt from this check?
