As further improvements, I am wondering :
* Whether linux-update-*config should display a warning/error when
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE is not used, instead of being
silent.
* Whether this configuration update shouldn't be done automatically
when one does "make linux-menuconfig" or "make linux-xconfig".
People have often found strange to loose their configuration changes
in Linux/Busybox/uClibc when they do a make clean.
But regardless of this discussion, I think your patch should be merged
as is.
