Using malloc-lib=jemalloc in MariaDB 10.4.16 breaks startup

I was using "malloc-lib=jemalloc" under the mysql_safe section of the my.cnf configuration file in MariaDB 10.4.15 and once I updated to 10.4.16 the startup fails with the following error:

[root@host ~]# service mysql start

Starting MariaDB.201105 05:54:31 mysqld_safe ldconfig command not found, required for ldconfig -p

/etc/init.d/mysql: line 264: kill: (6268) - No such process

ERROR!

I'm running CentOS 6.9 as my operative system and downgrading to MariaDB 10.4.15 immediately resolves this issue.
