Now that no ports use these common configure APIs, delete the logic
and remove it from the documentation.

 Generating "configure" files
 ============================
 
-For targets using the common framework, "configure" can be generated
-by running `autoconf'.
-
-To regenerate the configure files for all targets using the common framework:
-
-	$  cd devo/sim
-	$  make -f Makefile.in SHELL=/bin/sh autoconf-common
-
-To add a change-log entry to the ChangeLog file for each updated
-directory (WARNING - check the modified new-ChangeLog files before
-renaming):
-
-	$  make -f Makefile.in SHELL=/bin/sh autoconf-changelog
-	$  more */new-ChangeLog
-	$  make -f Makefile.in SHELL=/bin/sh autoconf-install
-
-In a similar vein, both the configure and config.in files can be
-updated using the sequence:
-
-	$  cd devo/sim
-	$  make -f Makefile.in SHELL=/bin/sh autoheader-common
-	$  make -f Makefile.in SHELL=/bin/sh autoheader-changelog
-	$  more */new-ChangeLog
-	$  make -f Makefile.in SHELL=/bin/sh autoheader-install
-
-To add the entries to an alternative ChangeLog file, use:
-
-	$  make ChangeLog=MyChangeLog ....
-
+"configure" can be generated by running `autoreconf'.
