[PATCH] IA-64 glibc TLS support

Hi Jakub,

I applied this patch and built libc with it and it worked fine
(cool!).  I then tried to add the new (flexible) syscall stub, which
requires a valid thread-pointer even for non-threaded applications.
Unfortunately, at the moment it looks like the thread-pointer does not
get setup for such apps (it stays NULL).  What's the right place to
get this initialized?

Thanks,
