Thank you Marc for figuring out the filtering-out solution!
It fixed the build on ChromeOS.
I will update the patch and also filter out `-fprofile-use` which will avoid
a similar problem with the instrumented PGO in the future.
Thanks,
Denis

I'm sorry, but I don't feel constrained by your internal deadlines. I

Hi Mark,
This problem currently blocks the PGO roll on the ChromeOS kernel and
we need some kind of a solution.

Kernel build with clang and KCFLAGS=-fprofile-sample-use fails with:
error: arch/arm64/kvm/hyp/nvhe/kvm_nvhe.tmp.o: Unexpected SHT_REL
section ".rel.llvm.call-graph-profile"
Starting from 13.0.0 llvm can generate SHT_REL section, see
