d'oh!

I could swear I did a `git grep
__unsafe_string_function_usage_here_size_t__` and it didn't return
anything. Well, looks like I was just being stupid. It's an
optimisation used in some Samba utility code and our waf configure
check didn't correctly report whether clang supports this
optimisation.

Sorry for the noise! :)
