Extended Description

Reported here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=972333

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? https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=4d8ee860737005517be588f4771c358593fa421c https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=e6f04d55f681149a69102a73937d0987719c3f16;hp=55b8e31a7a109bbd4efd7a59408c3c59dcf62ee0

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

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
