[OpenWrt-Devel] [RFC] [PATCH] build: honor command line CONFIG_ variables on kernel_*config targets

[Emmanuel Deloget]

The CONFIG_* variables are correctly handled when building nearly all
targets (at least packages and full build) yet they are not honored on
kernel_menuconfig and similar targets.

Some use case :

  make CONFIG_DOWNLOAD_FOLDER=../dl/ kernel_menuconfig
  make CONFIG_BUILD_SUFFIX=test kernel_oldconfig

and so on...

When used, they generate build errors because the kernel_*config targets
are not able to find the correct directories.
