It appears that AU_ALIAS is guilty. If I replace AU_ALIAS with AU_DEFUN in
the definition of AC_CANONICAL_SYSTEM is is updated correcly.

Let's see what happens. Look at the following definitions from
acgeneral.m4:

define([AU_ALIAS],
[AU_DEFUN([$1], defn([$2]))])

AU_ALIAS([AC_CANONICAL_SYSTEM], [AC_CANONICAL_TARGET])

This together essentially means - define AC_CANONICAL_SYSTEM to the
definition of AC_CANONICAL_TARGET. The later is not the same as the
literal "AC_CANONICAL_TARGET", so AU_DEFUN is called not with the same
arguments as in the _supposedly_ equivalent

AU_DEFUN([AC_CANONICAL_SYSTEM], [AC_CANONICAL_TARGET])

This patch works for me, i.e. autoupdate works and the testsuite still
passes. And even configure still works with old macros. However, it is by
no means a patch made by somebody who knows what he is doing :-)
