How are you configuring it?

You're downloading the source code by release tag, which is fine but it
doesn't have generated files such as configure.  If you download the
release tarball (eg
https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-8.2p1.tar.gz)
it'll have them.

Exactly what "cross-compiler settings"?

Every thing that you do without mentioning it here makes it harder to
figure out what's going on.
