Cross compilation with openssl > 1.0.2

[Andrey Strunin <acrapmonster@xxxxxxxxx>]

Hi,

Do you have any plans to fix the issue with libssh cross compilation with
newer openssl?
https://github.com/CESNET/netopeer2/issues/856#issuecomment-791481305

I need libssh library for libnetconf2 and netopeer and system we use should
not have old openssl.

Thank you in advance
