OK, I identified the problem. We need to use the gold linker on that constellation. gcc and old binutils. An other problem is, that freetype must be shared when building webengine and that's not recognized non config. I try to integrate that, if its ok.

Hey, not sure how long the fix might take, so could you share some more details please? I'm currently stuck with the same issue. I tried binutils from source, tag 2.31 as well as 2.40. In both cases I hit the freetype issue which I thought is unresolveable.

// I got the idea for binutils change from https://bugs.gentoo.org/683794

binutils bug was fixed at 2.31, 2.32, and 2.33 so i think the issue is only available on old debian systems. But now, to your issue; you only need to add -o freetype:shared=True to your build. That fixed the issue on my system.
