Per the documentation, any code you put after AC_OUTPUT is run after
config.status (and thus the subconfigures) have been run.  So you can
add shell code to your top-level configure.ac that summarizes whatever
it wants, and that code will execute (and thus output) after the
subpackage configure output.

However, it may be trickier to figure out how to make the parent
configure report the status of decisions that were only made within a
subconfigure (there's an obvious flow of information from parent to
child, but pretty much only exit status and scraping log files to get
information from child back to parent).
