That is also what I remember, and the FSF site confirms. But as it happens,
parts of OpenSSL may be under less restrictive licenses.

Their x86_64 MD5 states:

# MD5 optimized for AMD64.
# Author: Marc Bevand <bevand_m (at) epita.fr>
# Licence: I hereby disclaim the copyright on this code and place it
# in the public domain.

Their SHA for a lot of archs say:

# Written by Andy Polyakov <appro at fy.chalmers.se> for the OpenSSL
# project. The module is, however, dual licensed under OpenSSL and
# CRYPTOGAMS licenses depending on where you obtain it. For further
# details see http://www.openssl.org/~appro/cryptogams/.

The "depending on where you obtain it" is unusual for a license and
ambiguous, but the tarball proposed on this URL clearly proposes optimized
SHA-1 under, unless I am mistaken, 3-clause BSD license (LGPL-compatible).
