Thanks for the patches. I haven't looked in detail yet but I did try
running them through testing which revealed:

https://autobuilder.yoctoproject.org/valkyrie/#/builders/92/builds/1283

as well as some issues working with meta-clang:

https://autobuilder.yoctoproject.org/valkyrie/#/builders/18/builds/652

There are other patches causing issues in that build, I'll leave it
running in case it can spot any other issues with this patch series.

Cheers,

Richard
