branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This commit allows the user to store defconfigs in
$BR2_EXTERNAL/configs/. To achieve this:
* It adds a new %_defconfig that looks in $BR2_EXTERNAL/configs/ for
the corresponding defconfig file.
* Updates the help target to also list external defconfigs.
