Fixed that (I think) by setting BR2_SOFT_FLOAT=y.

Now it gets a further before it fails:

I'll probably just de-select the "at" package and try again.

Are there periodically checks to make sure the default configs
for the "supported" targets build successfully?

I wouldn't think it would take more than a dozen or two lines
of bash code to do so...
