i686 support being dropped

Its a long time comming, but we are discontinuing the last of i686 support, effectively immediately. i686 has been discontinued from upstream Arch Linux for some time, and we have been following the Archlinux32 project. The last two releases did not see an i686 release as the quality would be signifigantly less and some major packages like firefox-esr do not build at all. A direct port is no longer possible. a proper fork would require a lot of effort, for very little gain.

In addition there are errors like Archlinx32 not fully repackaging their perl packages for new versions, tripping errors. Many upstream repos and projects do NOT test for 32 bit x86 on linux anymore.

More and more PKGBUILDs start to fail.

Today, we hit OOM errors attempting to build packages, even with enough swap space installed, and the memory limit of the arch kernel with 4GB of ram is not enough to maintain this repo. To rememedy this, we would need to maintain a seperate kernel with PAE enabled, just for the build environment. While configuring a kernel is trivial, maintaining one is not. Especially when you maintain a seperate kernel for production.

All for less and less people actually using this obsolete archecture. We feel that 64-bit PC penetration is sufficient to make the change.

In the future, if Archlinux32 improves and we are able to make a full compile, we MIGHT, repeat MIGHT release a pentium4 fork. Pentium4 has the added benefit of SSE2 instructions, that might make this feasible to run on more modern 32-bit machines.
