Ok, I'll try to land the change later today.

I haven't run into those either. Looks like I've commented on https://github.com/llvm/llvm-project/issues/57718 at least. Not sure if that's caused by the same (too many sections, fixed by `-Wa,-mbig-obj`) or if it's a case where the string table exceeds 10 MB, which LLVM/MSVC handles fine but I think binutils hasn't implemented. If it is the latter, there's no fix other than implementing the >10 MB string table offset handling in binutils, or changing the build configuration to produce less data (e.g. not building in debug mode perhaps?).
