Because the script needs some generated files and rather to ask to the user:

  file X is missing, please run 'make prepare'

I just thought that it would be easier to let the script call make
prepare (this is just an example) automatically.

And from the script point of view, it's just easier to call make
instead of testing for all missing files.

But maybe it's just a bad idea.

Well I've never claimed that kbuild needs to be fixed.
