Comment (by kencu):

 For this, you unfortunately need to do a manual step to install `libcxx`
 with the `+universal_tls` variant. We have not as yet automated this
 process yet.


 Once you have a modern clang version installed through bootstrapping, at
 least clang-5.0 or better, if you do this, you should be good to go:
 {{{
 sudo port -v -n upgrade --enforce-variants libcxx +emulated_tls +universal
 }}}
