commit bde971a83bbff78561458ded236605a365411b87 upstream.
Kernel build with clang and KCFLAGS=-fprofile-sample-use=<profile> 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 https://reviews.llvm.org/rGca3bdb57fa1ac98b711a735de048c12b5fdd8086. gen-hyprel does not support SHT_REL relocation section.
Filter out profile use flags to fix the build with profile optimization.

I need this to properly compile 5.15.y stable kernels in the chromeos build system.
Now queued up, thanks.
