Mission ------- Build a crosstool-ng toolchain for i486. Use makepkg with patched PKGBUILDs for cross-compilation. We cannot run tests this way, as we don't assume the i486 is running on x64_64 (which it does, but for the sake of the general usage of the approach we MUST assume it doesn't!). Packages built for the chroot must be also accessible to the cross-compiler (for header files, tools and libraries). For this we unpack all generated chroot packages in the sysroot of the toolchain. x-tools and sysroot: the cross-compiler (cross-ng) and the installed packages (using bsdtar) in the sysroot of the toolchain. i486-root destination root, being the boot image of the temporary system for i486. The goal is to get to a self-contained system with as few packages as possible which allows a basic i486 to be built. This requires at least some development tools, pacman and some base system to be cross-compiled. We also want basic network connetivity, so we can use the i486 VMs or real i486 as build slaves. Also, having a minimal bootable ISO for the i486 system (or even a set of floppies or PXE boot via a boot floppy would be very useful). We cannot have kernel modules in a ramdisk or systemd for this basic system because they interfere heavily with memory constains on a 486! So, we build up to an openssh server. On top, the full Archlinux i486 universe can then be built (either with a i486 chroot or via a i486 master/ distcc slaves setup or a distributed i486 cluster setup). There is another caveat: we are patching the PKGBUILDs to do proper cross-compilation (--with-host, --with-target). Still we try to stay close to the original PKGBUILDs.
