"mariadb" consistently fails a single test on the core-updates branch on
armhf-linux:

https://ci.guix.gnu.org/build/1689172/details

The test output:

This does not happen on current 'master', so the problem was introduced
somewhere in between ccbc1c5eb..cbc8c658d.

I was able to work around it by going back to GCC 5:

GCC 9 did not make a difference.

Workaround pushed in 2fa55c72476c73211cbb2d6b29c05a1ad58a6cf9.  Let's
revisit this after upgrading to MariaDB 10.4.
