build: check without_ssl in warn openssl_no_asm

Currently when configuring --without-ssl  the following warning is
displayed:
WARNING: openssl_no_asm is enabled due to missed or old assembler.
            Please refer BUILDING.md

This commit adds a check of options.without_ssl to avoid this warning
when --without-ssl is used.
