[Buildroot] [PATCH 08/13] Store BR2_DEFCONFIG in .config, and use it to update the original input

From: Arnout Vandecappelle (Essensium/Mind) <arnout at mind.be>
defconfig file after updating the configuration.
Also use $(PROJECT_DIR) by default.
As a side-effect of this change, the *config options have been moved out
of the BR2_HAVE_DOT_CONFIG condition. Also, the defconfig and savedefconfig
targets do need to include .config now, which makes them slightly slower.
