Address some build errors this configuration throws up. Hi Ian, Thanks for the performance numbers. Any sense of what the build time numbers might look like for building perf with LTO? Does `-flto=thin` in clang's case make a meaningful difference of `-flto`? I'd recommend that over "full LTO" `-flto` when the performance difference of the result isn't too meaningful. ThinLTO should be faster to build, but I don't know that I've ever built perf, so IDK what to expect. -- Thanks, ~Nick Desaulniers
