libtool.texi: need_lib_prefix doc

[Ralf Wildenhues]

This description looks fishy to me: (use fixed-width font)

,-- doc/libtool.texi (libtool script contents)
|
| @defvar need_lib_prefix
| Whether libtool should automatically prefix module names with 'lib'.
| Set to @samp{yes} or @samp{no}.  By default, it is @samp{unknown}, which
| means the same as @samp{yes}, but documents that we are not really sure
| about it.
| @samp{yes} means that it is possible both to @code{dlopen} and to
        ^^^
Either this needs to be `no', or there is a `neither' missing in this
sentence..

| link against a library without 'lib' prefix,
| i.e. it requires @var{hardcode_direct} to be @samp{yes}.
| @end defvar

.. but since I haven't grasped the hardcode_direct addendum:
Which is the right way?
