There is no _POSIX_REGEX_VERSION, so don't check for it.  Instead
check for what actually exists, which is _REGEX_VERSION.  I found this
when trying to make the getconf environment variables typo-proof.

	* sysdeps/posix/sysconf.c (__sysconf): Check for and return
	_REGEX_VERSION and not _POSIX_REGEX_VERSION.

_REGEX_VERSION is never defined and in fact it was removed from the
standard.  For backward compatibility we must support _SC_REGEX_VERSION and
return -1 without setting errno, but I don't think we should treat this
like the real cases any more.  That is, just unconditionally return -1
and a comment about it having been removed in 1003.1-2004.


Thanks,
Roland
