bug#32511: mariadb 10.1.35 fails to build on x86_64

[ludo@gnu.org (Ludovic Courtès)]

Hello,

On berlin, mariadb 10.1.35 has one test failure (this is
/gnu/store/a5jm2hyalyblgjnxx5x3ly4fwvfivq5m-mariadb-10.1.35.drv, as
found in Guix commit b0cb92b2d43a2c4d5fa9b3f8c04c5732c60061e7, for
instance):

Complete log is at
<https://berlin.guixsd.org/log/37ldf3jfbq8qv0i0bpfrbbjd4ska605l-mariadb-10.1.35>.

Note that this failure, in turn, prevents qtbase and icecat from being
built, so we should probably find a quick stop-gap if that turns out to
be tricky.

Ideas?
