Peter Wemm 6c205e59db Delete the 'device-driver' suffix. It's been meaningless for a long time.
On the VAX, it used to be used for special compilation to avoid the
optimizer which would mess with memory mapped devices etc.  These days
we use 'volatile'.

# Generic makefile changes should be made in
