There is some sort of init function in libc which... see
/usr/src/lib/libc/gen/tls.c, _init_tls(), which appears to run
before anything else, at least for static builds. I don't like
the idea of not supporting the possibility that an initial TLS might
already be set-up before the RTLD runs, so I went for a generic
solution.
An even larger issue is the fact that we seem to repeat the TLS and
dynamic segment management code something like three times between
libc and rtld. I'd prefer that code to exist just once, though I
don't see an easy way to do it in just one place at the moment.
