I haven't tried to support static linked TLS at all. The plan is to get the kernel to size the TLS segment and add extra AUXARGs to report its size, initialiser location and alignment. The stubs in libc/gen/tls.c would be extended to provide support for allocating the TLS blocks in the static case. I was under the impression that no-one particularly wanted to support pthreads in statically linked binaries?
