Fix thread safety on mingw-w64 and clang
After finding a working TLS storage class specifier, configure was
continuing to test other candidates. This caused it to prefer
__declspec(thread) over __thread. However, __declspec(thread) is
ignored with a warning by mingw-w64 [1] and silently ignored by clang [2].
The resulting binary behaved as if PIXMAN_NO_TLS was defined.
Bug introduced by a069da6c.
