There is a subtle but nasty problem that a function's cwd can vary depending on whether ${B} (often ${S}) exists before the funciton is called or not. Most functions in the system can cope with this but its bad practise and I've just witnessed build failures resulting from this during image generation from bootimg.bbclass. I also suspect this could explain some odd fetcher behaviour witnessed in the past. This change ensures we always call funcitons with a specific build directory making things deterministic.
