Not really, Wang, we need to update that feature detection test to state what
is the minimum required LLVM/clang version, one that has those functions,
which, unfortunately, isn't the one in the latest fedora, fedora 25:
[acme@jouet linux]$ rpm -q llvm-devel clang-devel
llvm-devel-3.8.0-1.fc25.x86_64
clang-devel-3.8.0-2.fc25.x86_64
