Arnd, Olof, Please ignore this. I wanted to put this patch into Russell's patch tracker, but just sent it to a wrong ML.

To use Fastfpe, a user is supposed to enable CONFIG_FPE_FASTFPE and put downstream source files into arch/arm/fastfpe/. It is not working for O= build because $(wildcard arch/arm/fastfpe) checks if it exists in $(objtree), not in $(srctree). Add the $(srctree)/ prefix to fix it. While I was here, I slightly refactored the code.
