Poppler and Snow Leopard

[Ken Cunningham]

If poppler now requires thread_local, that is a significant change.

If you're using libstdc++, you can try building with gcc6 or gcc7. 

Luckily, I believe my TLS-enabling  modificatins for clang and libcxx for 10.6 and earlier are ptetty much ready for use. Passes all the llvm test suite test that it should pass.
