That's all perfectly fine. I was just pointing out that it was a known
situation.

Well, building a toolchain does not go with the snap of fingers.
As I said previously, there is *no* *sane* defaults to the config
options. So you can *not* rely on just setting a few options here
and there, you have to look at (almost) every other options...

Did you google for this error?

The bundled sample x86_64-unknown-linux-uclibc would seem to fit.

How to use samples:
  ct-ng "put the sample name here"

Eg. in this case:
  ct-ng x86_64-unknown-linux-uclibc

How to list all available samples:
  ct-ng list-samples
