Sergey Ryazanov bb9eb2c96e build: new fixes for symlinked .config handling
When running "make {config|defconfig|oldconfig}" with symlinked .config
(e.g. to env/.config) it renames symlink to .config.old, creates new
.config file, and writes the updated configuration into it.

This breaks the desired workflow when changes in the configuration can
be checked using "scripts/env diff" and commited using "scripts/env
save". Since the env/.config file is not updated.

The things become even worse when working with feeds, since feeds script
quite often silently invokes "make {oldconfig|defconfig}" and breaks the
symlink.

Fix this issue by exporting KCONFIG_OVERWRITECONFIG=1, which forces
mconf to overwrite the .config content, instead of renaming it and
creating a new file. This variable is set only if .config is a symlink,
otherwise the variable is not exported and the old behaviour is
preserved.

This change uses the same behaviour as "make menucofig", which has
already been fixed in commit 5bf98b1acc3b6b178f8954c5075a58e1e6a99d6a.

Also make a tiny cosmetic update to the "make menuconfig" target code
layout to make it look like other config handling targets.

This is the buildsystem for the LEDE Linux distribution.

Please use "make menuconfig" to choose your preferred
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl, make,
find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers.

Run "./scripts/feeds update -a" to get all the latest package definitions
defined in feeds.conf / feeds.conf.default respectively
and "./scripts/feeds install -a" to install symlinks of all of them into
package/feeds/.

Use "make menuconfig" to configure your image.

Simply running "make" will build your firmware.
It will download all sources, build the cross-compile toolchain, 
the kernel and all choosen applications.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system
(case-sensitive filesystem required). Cygwin will not be supported because of
the lack of case sensitiveness in the file system.
