* elf/dl-reloc.c (_dl_nothread_init_static_tls): Assert that dtv
array index is within bounds.
* elf/dl-load.c: Do not allow PT_TLS in modules loaded in statically
linked code.
* sysdeps/generic/dl-tls.c [!SHARED]: Don't build _dl_next_tls_modid.
* elf/Makefile: Remove rules to build and run tst-tls9-static.
