[PATCH] DON'T MERGE - add patch that fixes U-Boot host tools building

In U-Boot 2014.04 host tools building is sort of broken now.
One needs:
 1) Config an existing board
 2) Have corresponding to (1) cross tools in path

Even though logically host tools has nothing to do with target (cross) tools.
As soon as mainline U-Boot is fixed remove this patch.
