Can you please list which version of the Xilinx ISE tools you are using? e.g. 12.4, 14.1, 14.2 ?

Could you also please list the Xilinx development board that you are using? e.g. SP601 (Spartan6) ?

If you look at the tune file, it says TARGET_FPU = "soft", which means
software floating point emulation.

However, the gcc toolchain recipes are trying to build with hardware floating
point support, from the error message.

Let me know what you ISE development tool configuration and development
board is, and I'll see if I can divert a bit from target platform, and try to 
explore getting the toolchain to build for the Microblaze processor.

I've got the following boards with me:
- Xilinx ML507 (Virtex 5 FX70T with PowerPC 440)
- Xilinx SP601 (Spartan 6)
- Xilinx Zynq (ARM Cortex A-9)
