It seems it was caused by a new version of binutils (2.35.1-2 probably):
https://tracker.debian.org/news/1181645/accepted-binutils-2351-2-source-into-unstable/

Maybe these patches?

Please note that it is happening only on this arch on Debian.

And happening from version 8:
https://buildd.debian.org/status/package.php?p=llvm-toolchain-8
to 11:
https://buildd.debian.org/status/package.php?p=llvm-toolchain-11

Moving from gold to bfd as linker fixed the issue (ie NOT using -fuse-ld=gold)
