* This scripts, now runs only in x86_64.
* build.sh does not require arguments to run (no more build, clean, purge).
* /usr/share split is not done anymore: there are some differences between two arches. (ISO size +60MiB)
* /usr/lib/modules split is not done anymore: this was never enabled officially in aitab.

Tested and works fine. Maybe some small cosmetic changes needed.
