Can you add these lines too?

+BR2_KERNEL_HEADERS_VERSION=y
+BR2_DEFAULT_KERNEL_VERSION="3.7"

These are to lock down on kernel headers.
It's not a problem at the moment since the default buildroot version is
3.7.x, but this will change in the future when 3.8, 3.9, so on are
released and it's bad building a toolchain with newer headers than the
running kernel (eventual breakage).
Thanks!

+This the Buildroot support for the  LPC3131 based Gnublin board (see here:
+http://en.gnublin.org/) and for the Elektor Linux board
+(http://www.elektor.com/news/elektor-presents-embedded-linux-made-easy.2147294.
+lynkx)
+
+Unfortunately currently the AD and the pwm modules are not supported, i'm about
+to add also those drivers as well to the current kernel later.
+
+Base kernel version: 3.7 (available here:
+https://gitorious.org/linux-3-7-gnublin/linux-3-7-gnublin/commits/gnublin-
+support)
+
+U-boot version: 2009.11 (available here:
+https://gitorious.org/u-boot-gnublin-support/u-boot-gnublin-support)
+
+
+Steps to create a bootable SD card (with the given config you need an at least
+500 MB SD card):
+
+1.Config buildroot with the gnublin_defconfig:
+
+$ make gnublin_defconfig
+
+2.Tweak the config for your needs:
+
+$ make menuconfig
+
+3.Build:
+
+$ make
+
+4.Create two partitions on your SD card, one with type of BootIt (fdisk ID: df),
+the size should be around 1M, and another partition with all of the left space
+on the card, and with the type of normal DOS partition.
+
+5.From the output/images directory dump the u-boot image to the BootIt partition
+(probably you have to modify the output /dev files according to your system):
+
+$ dd if=output/images/u-boot.bin of=/dev/sdc1
+
+6.Dump the root fs image as well:
+
+$ dd if=output/images/rootfs.ext2 of=/dev/sdc2
+
+7.Insert the SD card into the board's slot, and your board should boot up with
+your newly created system.
+
