I don’t believe that this has actually never worked, or if it did appear
to work, it was only by accident. We have no ability to generate a
proper sysroot in the tree today, though we do come close at points.
Sean Bruno has been reporting issues with libgcc and external
toolchains for months, and I’ve not had the time to track those
issues to ground.

No. I don’t. While I handle many of the build issues, I haven’t
been looking at this one and it is likely beyond the time I have
available at the moment.

Also, the URL resolves to file not found for the logs.
