After investigating the alternatives, I think this patch is the best way
to fix this problem.  Using LLVM_CXXFLAGS introduces too many extra flags
and adding -fno-rtti globally breaks clover.  However, the -fno-exceptions
flag shouldn't be needed since gallivm does not use exceptions and this patch
also needs to be fixed so it works for all versions >= 3.2

With an updated patch applied we can revert the original fix:
