This patch actually tripped me up today. Turns out I have both:

 build/kernel/sched/core.o
 build/kernel/sched/.tmp_core.o

and ended up staring at the wrong file and going WTF because the offsets
didn't match.

I much prefer the actual real filename printed. Yes the .tmp_ crud is
weird, but at least its the real file.
