Agreed. I haven't seen any updates on this, but we need to fix the build
issues for 2020.08, so I've sent a patch to simply disable introspection
support:

https://patchwork.ozlabs.org/project/buildroot/patch/20200831140035.5880-1-peter at korsgaard.com/

We can then refine it later to add introspection support once the issues
have been fixed for next.
