Thanks for contributing this. In other code, I see people doing using a workaround that uses a different MARIADB_<mumble> macro to detect the same thing. Acccording to https://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-6.html, mysql_real_escape_string_quote() was introduced in MySQL 5.7.6, released in 2015. We're eight years later, and I see no evidence of any MariaDB version that implements this function.
