[waffle] [PATCH 0/4] Support XCode 3.1, which lacks TLS

[Chad Versace]

This patch series lives on my branch testing/support-for-no-tls at
git://people.freedesktop.org/~chadversary/waffle.git .

It adds code paths in wcore_tinfo.c to support development environments that
don't support thread-local storage. Clang < 3.2, for example, lacks TLS.

Nigel or Jeff, could you please test these patches with XCode 3.1? I currently
don't have a Mac system to test on (but that will soon be fixed).  I wouldn't
be surprised if I used some pthread features unsupported on Mac OS.

I tested the series on Linux with Clang 3.3 by running `make check-func`.
I tested once with WAFFLE_HAS_TLS defined and again undefined, to simulate an
environment without TLS. Both runs looked good.
