[Buildroot] [PATCH] Added microblaze patch

Arnout,
This is the patch with some minor adjustments. I've tested it using a big endian toolchain. Stephen used a little endian toolchain.
I got rid of the BR2_GCC_TARGET_TUNE as the build errored out when I attempt it with the raw patch. The error stated that target tune was not supported by the compiler.

+This is the buildroot board support for the Avnet Spartan6 LX9 MicroBoard.
+
+The board can be bought from Avnet or from Trenz for a low prize.
+
+To run the Linux built with buildroot you have to install the FPGA bitfile
+and the u-boot boot loader as described in the totorial available on
+
+ http://www.em.avnet.com/s6microboard
+
+The image file (default name is simpleImage.lx9_mmu.ub) has to be
+copied to your tftp folder (often /tftpboot/).
+
+Sample session:
+
+SPI Bootloader
+Loading binary image
+from flash @ address: 00060000
+to RAM address: 83f00000

+TODO list for the Spartan LX9 Microboard
+
+Generate u-boot within buildroot
+================================
+Currently, we need to use the u-boot provided by Avnet.
+
+Provide config files for qemu
+=============================
+
+Generate toolchain
+==================
+Currently the GNU toolchain provided by Xilinx has to be used.
+Xilinx does not provide a toolchain suitable to build a mmu-less
+Linux system, but omitting the mmu saved space within the FPGA.
+
+Bring up mmu-less system
+========================
+Hopefully this is easy as soon as we have a working toolchain
+with flt support.
