Wow, a question no one has ever asked before! In this case, recursion
refers to configure running itself in every subdirectory.
By default, if you run configure in a directory, it also tries to run
configure in all subdirectories that have configure scripts. The
-norecursion flag turns off this behavior. The config.status file
that gets left behind is a script that will be run by the Makefile
under certain circumstances (if there is a Makefile.in or a configure.in
that is newer than the Makefile), but we wouldn't want this re-running
to go off and change other directories; that's why the -norecursion
flag is present.
