- Add x86-64 support with all.img for now as other boot images are way

  too big at the moment
- Use isolinux on x86-64 too and stop deliberate call to boot_img_i386()
- Fix Makefile when BOOT_IMG only contains all.img
- "Macroize" references to ramdis_size
- Add symlink for /lib64 on lib64 architectures since that's not already
  in stage1-data/stage1.tar.bz2
