glibc/elf/tst-tls5.c
Roland McGrath 2d14868942 * elf/tst-tls4.c: Define an unused TLS variable here, so that no lazy
TLS setup is required.
	* elf/tst-tls5.c: Likewise.
	* elf/tst-tls6.c: Likewise.
	* elf/tst-tls7.c: Likewise.
	* elf/tst-tls8.c: Likewise.
	* elf/tst-tls9.c: Likewise.

	* elf/rtld.c (dl_main): Remove [! SHARED] conditional from
	`if (GL(dl_tls_max_dtv_idx) > 0)' tests for doing TLS setup.
	* elf/dl-close.c (libc_freeres_fn): Check GL(dl_tls_dtv_slotinfo_list)
	for being null before calling free_slotinfo.
	* elf/dl-load.c (_dl_map_object_from_fd) [SHARED]: For PT_TLS in
	dynamic loading, bail with error if GL(dl_tls_max_dtv_idx) is zero.
