Sure. So we need to decide whether it's worth support Blackfin in the
internal toolchain backend at all.

Great. But I've recently added a Buildroot-generated Blackfin external
toolchain in the autobuilder toolchain configurations, so we need to
decide if we want to support that or not.

From my point of view, since Blackfin already requires a very specific
combination of compiler + binutils version, it's a bit of a dead end in
terms of internal toolchain support, so we could just as well get rid
of it entirely.
