error: thread-local storage is not supported

[Ken Cunningham]

Well, I’ll be hornswaggled.

Indeed it appears the compiler.thread_local_storage option in MacPorts is well and truly broken. It basically only works on 10.6 and less (which is where I often am, so I guess it always worked for me).

Marcus forgot to blacklist command_line clangs < 800. 

We’ll have to get that fixed.
