It's not quite right.  You also need:

-for targ_alias in `echo $target_alias $enable_targets | sed 's/,/ /g'`
+for targ_alias in `echo $target $enable_targets | sed 's/,/ /g'`

(Thanks to Klee Dienes, who sent me some proposed autoconf conversion
patches last year.)

His other change in both binutils and gprof was to delete this from
acinclude.m4:

-sinclude(../libtool.m4)
-dnl The lines below arrange for aclocal not to bring libtool.m4
-dnl AM_PROG_LIBTOOL into aclocal.m4, while still arranging for automake
-dnl to add a definition of LIBTOOL to Makefile.in.
-ifelse(yes,no,[
-AC_DEFUN([AM_PROG_LIBTOOL],)
-AC_SUBST(LIBTOOL)
-])

If you're upgrading only autoconf rather than the full suite, I'm not
sure whether or not that is necessary.
