Given this file is unconditionally compiled, we would be better served
just adjusting min-tool-version.sh to show an error during configuration
time. Technically, this is only needed with LLVM_IAS=1 but that is the
default and adjusting as-version.sh to check the version would be a
little difficult but I will try to think about it more in the next few
days.
