Cross instructions

These instructions cover:

1. building a cross toolchain
2. populating the new ROOT
3. making it chrootable using qemu-user to easily run "native" builds or tests (this is like a stage3 at the end)

You do not need to follow through to the end if you don't need a stage3-like root.

Set up the toolchain

thesamesam

GCC

• Alpine Linux
• Arch Linux
• Debian, Ubuntu (on for most arches)
• Fedora does it via spec files globally, not via toolchain
• Gentoo (on for almost every arch by default, obviously in Gentoo you can toggle it easily if you want)
• openSUSE has an interesting gcc-pie package instead which provides a spec file
• Void Linux

LLVM

Hi all,

TL;DR: We really need help! There aren't many developers in Gentoo
interested in working on Itanium. Come hang around in #gentoo-ia64
on libera.chat (IRC) if you're interested in helping.

As discussed in the recent Gentoo Council meeting [0], concerns were raised
about the status of Itanium (IA64) and I agreed to write to gentoo-dev to
assess the level of interest & put out a call for volunteers.
