More clue in source/backend/frame.h
(in lines 1890+)

// platform-specific headers should have provided
DECLARE_THREAD_LOCAL_VARIABLE.
// if not, rather than generate an error, we will default to useing the
common
// __thread-style declaration. if your compiler throws an error on this
declaration,
// you'll need to fix your platform-specific config to provide a means
to declare
// thread-local variables. support for TLS is required for efficient
access by the
// render threads to their stats and cache data.
#ifndef DECLARE_THREAD_LOCAL_PTR
#define DECLARE_THREAD_LOCAL_PTR(ptrType, ptrName)       __thread
ptrType *ptrName;
#endif

But I'm afraid your compiler/os does not support per thread variables
(or if it does, it need to be instrumented in configure... )
