- No complex shell logic.
- "Source file shadowing" for all targets via vpath.
- Dependency handling.
- True incremental build.
- Don't write into source directories.
- Easy cleanup by just removing 'wrk'.
Note: These drivers are currently untested because I didn't realize that
using the drivers would need file routines, which are not available right
now. So in fact the drivers are not only untested, they are also unusable
on the target platforms, because they cannot be loaded.
