Unused by the Perl core.

As far as I can remember I added these scans long ago, for some
purpose (df(1) kind of APIs?) but whatever it was, it obviously
hasn't exactly caught fire in the last 15 years.

Some rare uses of these APIs (not these defines, but e.g. statfs)
in CPAN (like the Quota module), but those seem to do their own
configuration.
