OK, so we need to look at what's going on here.

Yes, perhaps we should do that. Not sure if it's too early to do that
or not.

If you look at http://autobuild.buildroot.net/?reason=ruby-2.4.1, this
issue only appeared two times: in July 2017 and August 2017. This
Sourcery toolchain has been around for much longer, and was last bumped
in December 2016.

So if it was just the Sourcery toolchain being unable to build
ruby-2.4.1, I think we would have a lot more failures than that. So it
might be a toolchain issue, but that occurs under very specific
conditions.
