Since e19d702b8e33, dlsym and friends use recursive mutexes that require the current thread id, which is not available before the libc constructor. This prevents us from using dlsym() in .preinit_array. This change moves TLS initialization from libc constructor to the earliest possible point - immediately after linker itself is relocated. As a result, pthread_internal_t for the initial thread is available from the start. As a bonus, values stored in TLS in .preinit_array are not lost when libc is initialized.
