The same happens with the amd64 build.
Any ideas?
All those are Clang-specific options which GCC doesn't understand, but, this
can't be the reason why your (LLVM-based) build is failing. As you can see
the test is in an `if' statement, so it shouldn't error-out.
Can you run the build again within script(1) so that the complete text is
captured, and we can see where the actual error is?
