Hi Fabin,
As a quick update, I was able to reproduce the issue on ppc64el with
Trixie. With below errors:

I'm currently testing the build with your suggested patches from
https://github.com/llvm/llvm-project/pull/184995
I'm also discussing this with PowerPC toolchain experts to better
understand
if there are any implications from the PPC side.
I will update here once I have more information.
Thanks,
Trupti
