No, the license demands that the clause 3 part of the license is
preserved together with the work itself:
* 1. Redistributions of source code must retain the above copyright
* notice, this list of conditions and the following disclaimer.
So you can't redistribute OpenSSL without including

both in the work itself (in the license), and on any auxiliary
material (advertising material).
That seems similar to cover texts to me: you can't redistribute a GFDL
manual with cover texts without including the cover text both in the
license text and on the cover page of the book.
I would count the book cover under auxiliary material -- the cover is
typically not part of the texinfo manual.
FWIW, to me, the GFDL requirement seems less problematic than the
OpenSSL requirement: the GFDL cover text requirement only applies to
the cover of books. It doesn't say anything about other advertising
material that is not derived from the work.

There is http://www.gnu.org/philosophy/free-doc.html although it
doesn't discuss license details.
