I was able to reproduce the issue locally.

Failure was happening due to Alistair Francis's patch from my v4 series 
(https://lists.openembedded.org/g/openembedded-core/message/229769) when 
applied together
with following patch "llvm: enable LLVMgold.so build by adding binutils 
dependency(https://lists.openembedded.org/g/openembedded-core/message/229387)"

To avoid this issue, I am dropping Alistair Francis’s patch 
(https://lists.openembedded.org/g/openembedded-core/message/229769<https://lists.openembedded.org/g/openembedded-core/message/229769>) 
from my patch set.
We will send a v5 series tomorrow.

Thanks,
Harish
