[2/2] Add correct variable names for _POSIX_IPV6 and _POSIX_RAW_SOCKETS
Commit Message
getconf only recognizes IPV6 and RAW_SOCKETS, when the standard
requires it to recognize the actual configuration variable name[1]. I
have not removed the earlier names for compatibility.
* posix/getconf.c (vars): Add _POSIX_IPV6 and
_POSIX_RAW_SOCKETS.

That looks OK. But we should consider as a cleanup removing all the
#ifdef's from getconf.c entirely. All configurations use the same
bits/confname.h, so there is no actual variation being tested here.
I'm not sure that POSIX actually allows us any leeway to omit any of
the _SC_* or _PC_* symbols. But even if it does, I can't really see
a reason why we'd want to let the GNU API vary that way.
