hurd: Fix x86_64 _hurd_tls_fork
It is illegal to call thread_get_state () on mach_thread_self (), so this codepath cannot be used as-is to fork the calling thread's TLS. Fortunately we can use THREAD_SELF (aka %fs:0x0) to find out the value of our fs_base without calling into the kernel. Fixes: f6cf701efc61c9ad910372bda14b9a235db310a8 "hurd: Implement TLS for x86_64" Checked on x86_64-gnu: fork () now works!
