support: move package/gnuconfig to support/gnuconfig

The CONFIG_UPDATE macro is no longer defined in
package/gnuconfig/gnuconfig.mk, but instead in
package/Makefile.autotools.in. It it also changed a little bit to take
the directory of the package sources as argument, and the AUTOTARGETS
infrastructure is updated to use this macro.

---- ABOUT ---
-This isnt a real package, it just exists to easily update the
-config.sub / config.guess files in packages to the latest version
-(since many bundled ones don't support the latest possible targets)
-
---- HOWTO ---
-To use, just add this to your unpack rule in the package.mk:
-$(CONFIG_UPDATE) $(PACKAGE_DIR)/
-
---- UPDATE ---
-GNU config is now managed in git, so to update:
-
-# git clone git://git.savannah.gnu.org/config.git
-# cp config/config.* .
-# for p in $(ls patches/*.patch); do patch -p0 < $p; done
-# rm -rf config
-
-A few local customizations are used to support uClibc so you may
-have to make sure they're still needed.  The patches are broken 
-out in the patches/ dir to keep things simple.

+--- HOWTO ---
+If your package uses config.guess and/or config.sub, then it probably
+relies on the autotools as its build system. In this case, you should
+use the AUTOTARGETS infrastructure, which will take care of updating
+the config.guess and/or config.sub files appropriately. See the
+Buildroot documentation for details about the AUTOTARGETS
+infrastructure.
+
+If for some reason your package does not use the AUTOTARGETS
+infrastructure, you can request the config.guess and/or config.sub
+files of your package to be updated by using:
+
+      $(call CONFIG_UPDATE,directory-of-your-package-sources)
