* sysdeps/generic/libc-tls.c (__libc_setup_tls): Make the phdr loop

	actually iterate over the elements.  Fix typo p_type -> p_vaddr.

	* include/pthread.h: Don't declare __pthread_initialize_minimal as
	weak here; we declare it weak or strong in the one place we use it.
	* sysdeps/generic/libc-start.c: ... which is here.
	Don't make the decl weak if [USE_TLS], since static programs need TLS
	setup even when single-threaded.
