There may be a trivial fix for this found in mariadb:
https://github.com/MariaDB/server/commit/a117030

and the corresponding mariadb upstream bug:
https://mariadb.atlassian.net/browse/MDEV-8131


It would be good to get this fixed in order not to leave
the HURD without a mysql server after the 5.5 -> 5.6 transition.
