I'll have a look at those. My previous attempts were using:

  https://wiki.linaro.org/ABE
  https://crosstool-ng.github.io/

I certainly don't want to be in the business of inventing yet another
set of scripts to build cross compilers!

Don't worry - not having every single architecture done isn't going to
stop the eventual submission. However it would be nice to have at least
one non-Debian cross-compiler setup as an example and to validate the
compiler-in-docker approach.
