config utility for Buildroot
I'm using the ./scripts/config script in the Linux kernel tree a lot. The script is used to manipulate a .config file from the command line which is quite nice to be able to do.
I use it mostly to enable configurations from a script or as a part of automated tests.
Buildroot is also using KBuild as its configuration system so I adapted this script and submitted a patch. It is now part of the mainline.
commit f2c5c7a263d9d61faba80544e0f6ac6da03716ee Author: Marcus Folkesson <email@example.com> Date: Tue Sep 26 23:15:02 2017 +0200 utils/config: new script to manipulate .config files on the command line Default prefix is set to `BR2_` but may be overidden by setting BR2_PREFIX. Example usage: Enable `BR2_PACKAGE_GNUPG`: ./utils/config --package --enable GNUPG Check state of config option `BR2_PACKAGE_GNUPG`: ./utils/config --package --state GNUPG y Enable `BR2_PACKAGE_GNUPG`: ./utils/config --package --disable GNUPG Set `BR2_TARGET_GENERIC_ISSUE` to "Welcome": ./utils/config --set-str TARGET_GENERIC_ISSUE "Welcome" Copied from the Linux kernel (4.13-rc6) source code and adapted to Buildroot. Thanks to Andi Kleen who is the original author of this script.

In addition to all commands found in he Linux kernel version, I also addes the --package config as a shortcut to operate on packages.
