How are you compiling/linking uboot, what options are you using?

When you load the SDK, you need to source the environment file, and then you 
should be using $CC/$LD from the environment as the compiler.  Calling the 
arm-... directly may lead to failures as the --sysroot parameter is not passed 
to the compiler.
