[Patch] Improve diags for "OpenSSL headers match library"configure test

[Ben Lindstrom]

Suggestion.  Can we seperate the tests?

OpenSSL header version you have is...<version number>
OpenSSL library version you have is..<version number>
Error: Header and Library conflict, please check for multiple version
installed.

Or something like that.
