Do not define this macro if it does not need to do anything.

GCC @code{-v} will print the thread model GCC was configured to use.
However, this doesn't work on platforms that are multilibbed on thread
models, such as AIX 4.3. On such platforms, define
@code{THREAD_MODEL_SPEC} such that it evaluates to a string without
