release: build.sh using recipe names

- in previous builds, a "default" package name was used
  which required post processing step to create packages
  for each distribution (different hosts or tools chains)
- rework the build process to create the package directly
  without having to repack the tarball.
- this requires the FBPACKTARGET changes in fbc/makefile
