Description of problem:
When FIPS is enabled on the system with "fips-mode-setup --enable", some hash/crypto functions become unavailable in openssl, such as for instance MD5.

Unfortunately, mariadb makes use of MD5 internally to create VIEWs in the DB. This causes mariadb to crash whenever MD5 is used internally.

The issue materializes for instance when one wants to bootstrap a mysql database on disk with mysql_install_db:

# mysql_install_db

220203 16:52:19 [ERROR] mysqld got signal 11 ;                           
This could be because you hit a bug. It is also possible that this binary   
or one of the libraries it was linked against is corrupt, improperly built,  
or misconfigured. This error can also be caused by malfunctioning hardware.

We will try our best to scrape up some info that will hopefully help         
diagnose the problem, but since we have already crashed,               
something is definitely wrong and this may fail.

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467871 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Version-Release number of selected component (if applicable):
mariadb-10.5.13-1.el9.x86_64

How reproducible:
Always

Steps to Reproduce:
1. fips-mode-setup --enable
2. reboot
3. dnf install -y mariadb-server
4. mysql_install_db


Actual results:
The mariadb server crashes while executing an initial bootstrasp SQL statement


Expected results:
The server shouldn't crash


Additional info:
It seems the very same issue has been reported upstream for Percona's fork of MySQL [1], and is claimed to be fixed, although I haven't looked at it so far.
