Cannot Build with OpenSSL 1.1.1f on Ubuntu 20.04 LTS

Start by reproducing the Cargo build on Ubuntu 20.04 with the reported OpenSSL 1.1.1f packages and environment variables. Inspect the openssl-sys build output and linker errors; done means the project builds without the reported SSL_read_ex, SSL_write_ex, SSL_CTX_ctrl, and SSL_ctrl failures.
