That wouldn't help when people link directly with -lpthread rather than
-pthread. _REENTRANT is not required for pthreads, so I don't think we should
depend on it.

Perhaps the header files could be changed to react to _REENTRANT, as that seems

-D_GLIBCXX_GTHREAD_USE_WEAK=0 appears to work, but is not officially supported.
It also only affects the code in the libstdc++ headers, not the code inside
libstdc++.so that checks __gthread_active_p.
