[Buildroot] [PATCH v2] merge_config.sh: merge also buildroot config files

From: Angelo Compagnucci <angelo.compagnucci at gmail.com>
This patch adds a way to merge buildroot config file programmatically.
It adds an option (-b, buildroot mode) to manage buildroot config files.
The buildroot mode changes the way the script looks for configurations
entries using the BR2_ prefix and modify the call to the make command
to be buildroot friendly.
