I am trying to do the next stage of my build: i.e. building xloader(u-boot-v2) that I can load over USB using Nishant Menon's utilities (pusb).

I went and downloaded the beagleboard version of uboot-v2 from:

I try to build using the following sequence of commands on my machine:

export ARCH=arm
export CROSS_COMPILE=arm-wrs-linux-gnueabi-
export PATH=/opt/WindRiver/wrlinux-3.0/layers/wrll-toolchain-4.3-85/arm/toolchain/x86-linux2/bin:$PATH

cd projs/u-boot-2.0.0-rc10

make omap3530_beagle_per_uart_defconfig
make -f Makefile ARCH=arm CROSS_COMPILE=/opt/WindRiver/wrlinux-3.0/layers/wrll-toolchain-4.3-85/arm/toolchain/x86-linux2/bin/arm-wrs-linux-gnueabi-

However when I do the last step I get the following error, which I do not clearly understand the cause.

I got similar results when I tried using the ELDK tools

[pgmutasi@ u-boot-2.0.0-rc10]$ make -f Makefile ARCH=arm CROSS_COMPILE=/opt/WindRiver/wrlinux-3.0/layers/wrll-toolchain-4.3-85/arm/toolchain/x86-linux2/bin/arm-wrs-linux-gnueabi-

The full log of what happens is also attached below. Do you know what I am doing wrong with this build procedure ?
