[patch]: recognize AC_LIBOBJ

[Jim Meyering]

Here's a patch to make automake recognize the new autoconf macro,
AC_LIBOBJ, that encapsulates this sort of code:

  AC_SUBST(LIBOBJS)
  LIBOBJS="$LIBOBJS strftime.$ac_objext"

With AC_LIBOBJ, you just do this:

  AC_LIBOBJ([strftime])

--------------------------
I'll check it in tomorrow unless I hear an objection.

        * automake.in (scan_one_configure_file): Recognize AC_LIBOBJ.
