In practice I think it means "utilities whose existence are needed to
run 'configure' and 'make'".  (Somewhere between the two, as one could
in theory bootstrap by first building coreutils.)

This particular case is only weak evidence that 'dd' needs to be in
the list, since the code uses 'dd' only when /dev/urandom is readable,
and I expect that 'dd' is supported everywhere /dev/urandom is.
