Comment (by kencu):
that's what happens when you try to build libcxx with gcc (which is fairly
easy to fix, BTW, but that's another story).
Now libcxx does build and install on 10.5 Intel, exactly the same as it
does on 10.6.8 in fact. (Builds with clang-3.4 initially, then upgrades to
the +emulated_tls version using the current latest clang-5.0
+emulated_tls. I have it installed like that, as does Riccardo.
So it's a default compilers / blacklisting / fallback compiler selection
thing on 10.5 Intel... always a bit of a PITA given our desire to not
whitelist compilers.
