But you are aware of the configure.gnu "trick"?  See info Autoconf
Subdirectories for the semantics.

The trick is: you adjust the flags in subpkg/configure.gnu, then call
subpkg/configure with them.  The subpkg/configure.gnu file might
actually belong to the toplevel package.  A hack, but fairly easy.

I like the idea of a more flexible AC_CONFIG_SUBDIRS replacement, but
the suggested API does not really look appropriate yet, with all the
finer details of precious variables, (non-)shared config.cache handling
and so on still needing sane and precise semantics.
