The license on the 2 asm files from openssl the explicitly states:
@ ====================================================================
@ Written by Andy Polyakov <appro@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/.
@ ====================================================================
If you follow the URL for the CRYPTOGAMS license and read the actual license
at the end of the file it is very clearly dual licensed. So I think it is
ok :-)
Cheers,
Davidm
