Discarded Patch: 2006032121380929687

Stefan Fiedler:
        rockinitrd: 
        - cross-compile rockinitrd in stage 1
        - re-add support for ext2 as initrd fs, experimental support for 
          initramfs; introduce -fs option
        - use readelf instead of ldd: this allows to "cross-build" initrds,
          given that cross-readelf is in your PATH, together with the -root
          and -cross options (use e.g. -root build/<cross-build>
          -cross <arch>-unknown-linux-gnu-, and point your PATH to
          build/<cross-build>/ROCK/tools.cross/crosscc)
        - use file -L instead of file, so symbolic links to shared libraries
          are followed
        - file copy mechanism revised: always copy symlinks as is, not the files
          they point to; similarily copy device files, not their contents
        - some other cleanups and simplifications
