Thanks for the report and sorry for such a late reply. I can reproduce this with the newest version as well. I'm afraid that the clang team in Gentoo is understaffed right now, and we're unable to handle issues of building various packages with clang ourselves. I'm CC-ing the package maintainers in case they'd be interested in the issue but since clang is not officially supported, they're not required to take any specific action. If you could report the issue upstream, that would be great. If you could provide a working patch, that would be even better. Otherwise, I'm afraid we aren't be able to fix the issue anytime soon.
upstream clang people are already looking into making glibc build. Gentoo isn't really going to be carrying our own patchsets to make it work.
