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
