This was one problem. For libraries, `mmake depend' reads the `.int'
files to get the dependencies (in modules__read_dependencies), which will
miss the implementation dependencies required for reading the `.opt'
files transitively.  It may be possible to fix this problem by reading
the `.opt' files in modules__read_dependencies instead. This problem will
be fixed properly by `mmc --make'.
