That still doesn't work when building tools for the target:
/bin/sh: scripts/basic/fixdep: cannot execute binary file: Exec format error

I guess you are missing the point of this patch, as sandbox_defconfig will 
only eliminate dot-config=0 parameter, but not the need to build fixdep 
separately with a different host compiler...

On the other hand - is it a real requirement to build mkimage for the target?
