File openssh-7.6p1-disable_openssl_abi_check.patch of Package openssh.21986

# HG changeset patch
# Parent  f22dd231807395dc77507fd9baf4ad64ef34fa7a
disable run-time check for OpenSSL ABI by version number as that is not a
reliable indicator of ABI changes and doesn't make much sense in a
distribution package
