The ld.so bits have been committed last week. So here is a new
version of the diff. This version exports __cxa_thread_atexit_impl
such that gcc picks up our implementation. __cxa_thread_atexit
becomes a weak alias such that static linking succeeds. I rebuilt the
gcc 4.9 port with this diff and

Note that without providing __cxa_thread_atexit, gcc will not
Here is an update diff that implements __cxa_thread_atexit which is
emitted by clang (and modern gcc) to implement certain aspects of
C++11 thread_local.
Compared to the previous function this now also prevents unloading of
shared libraries that call __cxa_thread_atexit.
As before uou'll ne

The diff below implements __cxa_thread_atexit(). Calls to this
function are emitted by the compiler to schedule running desctructors
for thread_local objects when a thread terminates or calls exit(3).
The Linux implementation prevents unloading of shared libraries that
registered such destructors
