Thomas Petazzoni 6713fbd330 support/gnuconfig: update config.{guess, sub} to a newer version
We need more recent versions of config.guess and config.sub in order
to support the aarch64 architecture. Otherwise, all autoconf packages
fail to build with failures like:

  http://autobuild.buildroot.org/results/abcdbe1aaf1c203c82dc3e4ec8c002b9b9e550e0/build-end.log

We take this opportunity to turn the config.* patches into proper Git
patches, and note which Git commit of the config.git repository we
used as the original source.

--- 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 autotools-package infrastructure, which will take care of updating
the config.guess and/or config.sub files appropriately. See the
Buildroot documentation for details about the autotools-package
infrastructure.
If for some reason your package does not use the autotools-package
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)
--- 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 -p1 < $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.
The current Buildroot version is based on the Git commit
9582436dfae5755279f96898ce30bde28e4e69ea of the config.git repository.
