I suspect that that will fix it since `llrint` is a C99 function. If that does work, please let us know so we can fix things up. And if it doesn't work, please open an issue at https://github.com/numpy/numpy/issues/ and Cc me (@rgommers); the issue tracker is a better place than the mailing list to work through build problems.
