I totally agree.
I'v been looking at existing maintained images we can use to
cross-build, so we only have to pull (download) and image and use it,
not wasting cpu time building it.
However some images might be huge, full of things we don't need. But I
prefer that rather than having to maintain cross toolchains.
An example I like to use is the coreboot-sdk, designed to build
i386/amd64 binaries, it fulfills our needs. But takes 2GB...
$ docker pull coreboot/coreboot-sdk:1.47
1.47: Pulling from coreboot/coreboot-sdk

d23c9a72f1e5: Waiting
Another candidate is crossbuild, ~1GB
$ docker pull multiarch/crossbuild
