I think this one should be resolved by now with

That's a strange one, so far I was not able to reproduce it locally,
but will look at it a bit more next week.

What's especially strange it was the one and only failure on "busybox" package
out of many others that completed successfully, see?http://autobuild.buildroot.net/?reason=busybox-1.27.2

So maybe just forget about it and see how it goes.
What do you think?

This one should be fixed with arc-2017.09-release, see Eugeniy's patch here:

Interesting, I'll look at it soonish.

I think we saw something similar, let me check what's going on there.

Let me first see what is that and if something is really missing.
I mean why we don't have?FE_INVALID & friends defined.
