don't get me wrong - but that is a joke
looking at the commented line there was even a "-DWITH_JEMALLOC=system"
planned and later dropped - that is not how linux systems should work
if there is a security bug in whatever bundeled library and the distribution
is pushing a update mariadb will still use the vulnerable version and that
is why linux-distributions would use "-DWITH_JEMALLOC=no" if they can't
patch around this upstream bug to not violate packaging guidelines
the solution is support "-DWITH_JEMALLOC=system" and if it does not work with
"jemalloc-3.4.0" this is a bug because dbmail and Apache Trafficserver are doing
