I'm afraid in order to give good advice we need to know more about your
setup.

You say you would like your top-level configure script to invoke the
other configure scripts first, and then afterwards do its tests.  Why
would that help you?  Do the tests of the toplevel configure script
depend upon the config.status files that are generated by the sub-
configure scripts?  (I think this is a rather rare case in practice;
it could be solved by invoking the sub-configure scripts manually
instead of using AC_CONFIG_SUBDIRS.)

Or is it rather the case that your top level configure script should
only be run after the sub-packages have been _built_ (and not only
configured)?  (For example so that some libraries already exist.)

If the latter is the case, then I suggest you modify your toplevel
configure script so that it can just assume the libraries to exist.

Maybe it helps if you describe the actual problem you are trying to
solve.

Cheers,
