* sysdeps/generic/ldsodefs.h (struct rtld_global): New member
	`_dl_tls_static_used'.
	* sysdeps/generic/libc-tls.c (_dl_tls_static_used): New variable.
	(__libc_setup_tls): Initialize it.  Let the initial value of
	_dl_tls_static_size indicate some surplus space in the computed value.
	* elf/dl-open.c (_dl_tls_static_size): New variable.
	* sysdeps/generic/dl-tls.c (_dl_determine_tlsoffset): Initialize
	_dl_tls_static_used.  Add some surplus space into _dl_tls_static_size.
	* elf/dl-reloc.c [USE_TLS] (allocate_static_tls): New function.
	(CHECK_STATIC_TLS): Use it.
	* elf/dl-close.c (_dl_close): Adjust _dl_tls_static_used when the
	closed objects occupied a trailing contiguous chunk of static TLS area.
