build warnings

[Werner LEMBERG]

Unfortunately, the lilypond build system exceeds the complexness of
both groff and Freetype by some orders of magnitude -- and both are
already quite complicated.  Were it easier to understand I would try
to fix it by myself...

The very first message of the build process is repeated very often.
Any chance that this is fixed?

  lilypond/stepmake/stepmake/generic-targets.make:142:
    out/dummy.dep: No such file or directory

It occurs zillion times...
