* descr.h (struct pthread): Move the union out of [!TLS_DTV_AT_TP], so
	we always define the padding space.

	stopped supporting its own extensions fully.
	[TLS_MULTIPLE_THREADS_IN_TCB]: Put `multiple_threads' inside a wrapper
	struct also called `header', so `header.multiple_threads' is the field
	name to use on all machines.
