If you're not on a Debian-based distribution, that is :).

You can just install Debian into a systemd-nspawn chroot with the help
of debootstrap. No need to use Docker or anything else. I have used
this method to install and boot Fedora Rawhide on my Debian unstable
system. Pretty nifty and simple:
# debootstrap --no-check-gpg --arch=amd64 --variant=buildd unstable /srv/unstable/ ftp://ftp.debian.org/debian
# systemd-nspawn -bD /srv/unstable
That's all you need to boot a Debian container on any machine running systemd.

Does that really make such a difference? I have always used the gcc
versions shipped in Debian and never had any issues. Matthias Klose
also updates them very regularly, so I don't have to worry about

We're thoroughly testing the toolchain in Debian on the buildds. By
actively building packages, we have found many bugs in gcc and binutils,
most of them were in the SH and SPARC targets though. I don't remember
running into any m68k-related toolchain issue.
Btw, there is one additional advantage using Debian for cross-platform
work: Multi-Arch. You can easily install build dependencies when
cross-building for other targets. I have used this extensively to
bootstrap ghc .
