- thinking loud about auto-generating dependencies for make(1)
  Don't use this, it doesn't work yet. Thoughs welcome.
  Like: We should probably use the sym->text and not fiddle with the name since
  the name looses information ('_' != '-' in host-fakeroot). This would not
  be too robust, i fear, since the name can contain additional, arbitrary info.
  Also, the real 'depends' are a little bit ugly in kconfig. There doesn't seem
  to be a nice property that holds reverse deps that are only contain selected
  symbols.
  Thoughts?
