* sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Define
_dl_sysinfo_dso under [NEED_DL_SYSINFO_DSO] as well.
* elf/rtld.c (dl_main): Set up GLRO(dl_sysinfo_dso) under
[NEED_DL_SYSINFO_DSO] as well.
* sysdeps/generic/dl-sysdep.c (_dl_show_auxv): Always include
AT_SYSINFO and AT_SYSINFO_EHDR in name table.
(_dl_sysdep_start) [NEED_DL_SYSINFO_DSO]: Match AT_SYSINFO_EHDR.
* elf/dl-support.c (_dl_sysinfo_dso): Define also under
[NEED_DL_SYSINFO_DSO].
(_dl_aux_init) [NEED_DL_SYSINFO || NEED_DL_SYSINFO_DSO]:
Match AT_SYSINFO_EHDR and set GL(dl_sysinfo_dso).
