i686 to be phased out on Arch Linux

Welcome to ghorr, your source for GNU/Linux!  Arch Linux is looking to phase out support for the i686 architecture from the installation ISO, encouraging everyone to migrate to x86_64. Support will still be provided until November 2017 though. The [multilib] repository will remain functional.
