Revert architecture support in preflight.sh, to keep i686

[guyzmo]

Since 0.15, the preflight.sh script had a new condition forcing the host architecture to be x86-64, whereas all applications required for MIAB run as smoothly in 32bits as they do in 64bits. The only reason we'd need to run as 64bits is if the machine has a lot of RAM available.

I suggest to change the check so it becomes:

if [ "$ARCHITECTURE" != "x86_64" ] && [ "$ARCHITECTURE" != "i686" ]; then

within preflight.sh. I'll make a PR when I have a couple of minutes to spend on that.

Never crossed my mind! Sorry about that. Let me know if you don't get around to the PR since it was my PR that caused this.

well, I already hacked it in my prod instance, and the upgrade went fine, I just need to write it in a patch in my dev instance to be able to push it ☺

I created a pull request for it.

Thank you a lot, I did not do it because I have been away from keyboards and wifi and 3G for a week and I just came back ☺

No problem!
