    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.
