Would it help if Autoconf supported environment variables to support 
specifying the config.guess and config.sub scripts to use (similar to 
CONFIG_SITE and CONFIG_SHELL)?  For example, there could be 
CONFIG_SITE and CONFIG_SUB environment variables.  This approach would 
allow the package build wrapper to cause updated scripts to be used 
without needing to replace stale files which might happen to be in the 
package.  It seems easier for the package build system to specify what 
it wants to be used rather than hope that rules built into the package 
will select the desired version.
