Fix build targets in Makefile.prebuild 

- config.h was used as target even when it wasn't generated.
  This only worked because the 'dummy' target always triggers
  a full rebuild.
  It is however better to specify the exact target that is to
  be rebuilt do avoid confusion.
- Explicitly mark 'dummy' as a 'phony' target.
