Add dependencies on the VERSION file

- this fixes issue where some of the binary objects would contain an
  outdated MAGIC_VERSION if "make clean" was not done after the VERSION
  file changes. (e.g., the "Magic VERSION revision REVISION" message in
  the wish console and the version requirement checks from a tech file)
