Yeah, I do not think that would be a good solution --- it would give wrong
answers on three of my four buildfarm animals :-(, for precisely the
reason that they're using --with-libs to point to a non-system openssl
installation.
Is there a simple way to ask the library itself for version info?
It might be worth the cycles to have configure run a small test
program to extract and print that data (not on cross-compile
builds, of course).

Hmm, is it worth the trouble to fix that?

gaur and prairiedog are both building with 0.9.8x, as you can tell
from their --with-libs options.

According to the commit log (see 593d4e47d), we require 0.9.8 or later
in v10 and up, so any older animals got upgraded or retired some time
ago.
