SF2 on bionic fails audio test

[Tim Janik <timj gnu org>]

Hi Stefan,

I've added ubuntu 18.04 (bionic) to beast's travis-ci build matrix and it fails
b/c of a sf2 similarity mismatch:

        https://travis-ci.org/tim-janik/beast/jobs/383605840

This can also be reproduced in docker, just run:

        misc/dockerbuild.sh ubuntu:bionic gccbuild

Can you please look into that and make a suggestion how to resolve the issue?
