* sysdeps/i386/tls.h (TLS_INIT_TCB_SIZE, TLS_INIT_TCB_ALIGN): Define to

	size/alignment of struct pthread rather than tcbhead_t.
	* sysdeps/x86_64/tls.h (TLS_INIT_TCB_SIZE, TLS_INIT_TCB_ALIGN):
	Likewise.
	* sysdeps/s390/tls.h (TLS_INIT_TCB_SIZE, TLS_INIT_TCB_ALIGN):
	Likewise.
	* sysdeps/sparc/tls.h (TLS_INIT_TCB_SIZE, TLS_INIT_TCB_ALIGN):
	Likewise.
