* elf/tst-tls-dlinfo.c: New file.
* elf/Makefile (tests): Add it.
($(objpfx)tst-tls-dlinfo): Depend on $(libdl).
($(objpfx)tst-tls-dlinfo.out): Depend on $(objpfx)tst-tlsmod2.so.
* dlfcn/dlfcn.h (RTLD_DI_PROFILENAME, RTLD_DI_PROFILEOUT): New enum
values, reserve unsupported requested names used on Solaris.
(RTLD_DI_TLS_MODID, RTLD_DI_TLS_DATA): New enum values.
(RTLD_DI_MAX): Likewise.
* dlfcn/dlinfo.c (dlinfo_doit): Handle RTLD_DI_TLS_MODID and
RTLD_DI_TLS_DATA.
* elf/dl-tls.c (_dl_tls_get_addr_soft): New function.
* sysdeps/generic/ldsodefs.h: Declare it.
* elf/Versions (ld: GLIBC_PRIVATE): Add it.
* elf/link.h (struct dl_phdr_info): New members dlpi_tls_modid,
dlpi_tls_data.
* elf/dl-iteratephdr.c (__dl_iterate_phdr): Fill them in.

Instead, #include it while #define'ing around link_map.
* elf/dl-debug.c (_dl_debug_initialize): Add a cast.
Add bogus extern decl to verify link_map members.
* elf/loadtest.c (MAPS): New macro, cast _r_debug._r_map.
(OUT, main): Use it in place of _r_debug._r_map.
