[Buildroot] [PATCH] configs/riotboard: remove defconfig

[Thomas Petazzoni]

This defconfig fails to build with gcc 6.x, even though we switched to
using gcc 6.x as the default gcc version in May 2017.

This defconfig also hasn't seen any non-mechanical update since
November 2015.

So it's time to get rid of it, in order to remove the following build
failure:

-Buildroot for Embest RIoTboard
-==============================
-
-1. Compiling buildroot
-----------------------
-
-make riotboard_defconfig
-make
-
-2. Installing buildroot
------------------------
-
-Prepare an SD-card and plug it into your card reader. Write the bootloader to
-your SD-card:
-
-sudo dd if=output/images/u-boot.imx of=/dev/sdX bs=1k seek=1
-
-Create 1 partition on the SD-card using your favourite tool. The
-partition should be big enough to hold your rootfs, for example
-128MiB. Here's an example partition layout:
-
-   Device Boot      Start         End      Blocks   Id  System
-/dev/sdX1            2048      264191      131072   83  Linux
-
-Format the SD-card partition with your favourite filesystem:
-
-sudo mkfs.ext2 /dev/sdX1
-
-Deploy your rootfs to the SD-card:
-
-sudo mkdir /mnt/sdcard/
-sudo mount /dev/sdX1 /mnt/sdcard/
-sudo tar xf output/images/rootfs.tar -C /mnt/sdcard/
-sudo umount /dev/sdX1
-
-3. Running buildroot
---------------------
-
-Position the board so you can read the label "RIoTboard" on the right side of
-SW1 DIP switches. Configure the SW1 swiches like this:
-
-10100101 (1 means ON position, 0 means OFF position)
-
-Now plug your prepared SD-card in slot J6. Connect a serial console (115200, 8,
-N, 1) to header J18. Connect a 5V/1A power supply to the board and enjoy your
-new toy.
