You should build it once with Crosstool-NG outside of Buildroot,
install it somewhere, and tell Buildroot to use it as an external
toolchain.

That sounds really odd. Maybe we have a bug in the ct-ng backend, and
it doesn't copy the libraries? I would have to do a test build, but I'm
on the battery in the train for now, so I can't do heavy builds for now.
If someone could do a quick test build of a minimal system that uses
the ct-ng backend, and verify that $(O)/target/lib contains the right
libraries, that would be nice.
Best regards,
Thomas
