I have thought about and couldn't find any other benefits of putting the
vDSO entry onto the _ns_loaded.  To properly populate _ns_loaded,
we need to duplicate rtld.c's GLRO(dl_sysinfo_dso) handling in
dl-support.c, which calls other dynamic linker functions.  I don't know
if they are all supported in libc.a.  I can give it a try.
