Add --without-openssl-version-check to configure args to avoid this

I am sorry I should have been clearer, the ASA software is now using
openssl 1.0.1e according to Cisco's release notes.

Anyway, like a puff of smoke in the wind the problem just up and
disappeared on me. So it looks like the problem must be on my client
end somewhere. 5.99 seems to be working just fine against ASA software
9.2.1.

Thanks for the response and sorry for the noise,
