Mariadb – Install MariaDB 10 Generic Binaries + TokuDB

I used to install MariaDB from Generic Binaries on a Debian Wheezy 64bits:

mariadb-10.0.13-linux-x86_64.tar.gz
(from downloads.mariadb.org)

I would like to use TokuDB as Storage Engine.

However, TokuDB is available in "glibc_214" generic linux package as well as .deb packages, but it is NOT available in "non glibc_214 generic linux package"…

I can't use "mariadb-10.0.13-linux-glibc_214-x86_64.tar.gz" because Debian Wheezy glibc is 2.13:

$~: ldd --version
ldd (Debian EGLIBC 2.13-38+deb7u4) 2.13

Why is TokuDB not available in standard 64bits version of Generic Binaries?

Is it safe to copy ha_tokudb.so from an debian wheezy apt install (/usr/lib/mysql/plugin/ha_tokudb.so) to a generic linux "manual" installation (in ./lib/plugin)?

If I do so, I can enable TokuDB and all seems to work (I hope so anyway…):

(none)=# INSTALL SONAME 'ha_tokudb';
