if [[ ${bb_full_target} == *-sanitize+memory* ]]; then
    # Install msan runtime (for clang)
    cp -rL ${libdir}/linux/* /opt/x86_64-linux-musl/lib/clang/*/lib/linux/
fi

So, the script expects that if the target has sanitize+memory it is x86_64-linux-musl. But the runner that fails is actually x86_64-linux-gnu-sanitize+memory, not musl; and indeed, there is no musl runner with sanitize+memory.

I feel like I need a bit of background information here.

Problem is that we don't have msan libraries in our compiler-rt build of LLVM 16, so we need to pin llvm 13
