[PATCH 1/1] Just warn if linked libssl is more recent

[Christian Hesse]

From: Christian Hesse <mail at eworm.de>

Even if dynamic linking is just fine, radiusd fails after ever openssl
update. (Distribution toolkits do not detect this, so distribution
packages break on a regular basis.)
This changes behavior so that it still fails on library downgrade, but
just warns if openssl library has been upgraded.
