That's an argument for a general solution to the problem,
not a one-off bandaid fix for the bit that happened to
bite you.

I forget the exact failure mode but I think the problem
is that the old arm-softmmu/foo.d file is still lying
around and claims that foo.o depends on the no-longer-present
hw/foo.c. (If we didn't squash the directory structure, so
that it was arm-softmmu/hw/foo.d and arm-softmmu/hw/foo.o,
this problem wouldn't happen.)
