You don't need a configure.ac in every subdirectory. If your top-level
configure.ac does all the checks you need, then that's enough. All the sources
in the subdirectories can use the generated config.h.

You need SUBDIRS in Makefile.am, to get the generated Makefiles to recurse
into subdirectories and do whatever they do there (e.g.: build from sources).

I think AC_CONFIG_SUBDIRS is used when a package includes other packages that
have their own configure scripts, e.g.: gdb, binutils, gcc.
