[schilytools] Smake doing dependencies twice.

[Friedhelm Mehnert]

Hello,

there is a mysterious thing I'm wondering about for some time.

When building the Schilytools on Linux, Schilymake always does it like
this:

As you can see, it does the dependencies TWICE.

Gmake does not do this. It also seems to do the dependencies
"backwards".

I have looked through the source and done some experimenting, but I can
not find out, why this happens.
