I agree.  I notice many of these failing tests are for the TokuDB
backend, which I doubt anyone is using in Guix anyway.

Here is a patch that disables all tests mentioned in this report.  I
would like to push it to core-updates.  Are there others?

WDYT?

Note that the latest MariaDB is 10.4.x, and these tests may well be
fixed in later versions.
