Doesn't each multilib get its own build subdir?
Can't the file be copied there instead and thus get rid of this wart?

It would need an additional per-multilib directory in the include path. It's simpler for now to leave it as is, and it will go away as soon as nothing in the gcc directory will need unwind.h. Rainer has already removed countless dependencies between gcc and libgcc, adding one is not too bad.
