Supplied jemalloc results in immediate MariaDB Segfault on aarch64

mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

[Note] /usr/sbin/mysqld (mysqld 10.0.37-MariaDB) starting as process 30510 ...

<jemalloc>: Error in munmap(): Invalid argument

[ERROR] mysqld got signal 11 ;

This is likely to do with aarch64 on EL7 defaulting, against all sanity, to 64KB pages. Unfortunately, it is what it is.

AFAICT, it is directly related to this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1545539
Unfortunately, that bug long postdates EL7, so a better, working jemalloc will likely need to be supplied.

Also:
MariaDB supplied jemalloc is the same as EL7 aarch64 EPEL jemalloc (same version, broken in the same way).
