Oh, I personally only ever use distro-provided toolchains (when they
exist). The ones the distros use to build themselves. And I'm still
annoyed by how we're treating ARM like some weird special case that
needs to be cross compiled by default.
But that seems to be a lost battle. And I'd rather have the people who
feel that way use toolchains that occasionally get updated rather than
lock down on a version that stopped being updated several years ago.

Yes, hence my reference to downstream platforms :)
