It seems to me AC_PROG_LIBTOOL contains all the necessary
machinery to solve this ordering matter.  So if something change
with the order, I'd say it's a Libtool bug.

Automake should not have to keep track of every third-party
macro that depend on its.  Similarly Autoconf do not call
AC_BEFORE in AC_PROG_CXX and AC_PROG_F77.
