# Pre-load OpenSSL libraries so they're available when MariaDB loads plugins.
# MariaDB authentication plugins (e.g., caching_sha2_password) depend on OpenSSL,
# but when MariaDB loads them via dlopen, the dynamic linker can't find OpenSSL
# because it's in a different artifact. By loading OpenSSL with RTLD_GLOBAL first,
# its symbols become available to subsequently loaded libraries.
