sbuild works fine for native builds on amd64, but fails for cross-builds
(sbuild --host=arm64) with the following error:

I get the same error message when i try to cross-build other Java packages like
tuxguitar-1.2 or pdfsam-4.3.4 from the Debian sources.
The same happens with 'pdebuild -- --host-arch arm64'.
It seems that the dependency resolver tries to install <package>:arm64, but
fails because the package is architecture-independent <package>:all.
The package inetutils-2.4 builds fine with 'sbuild --host=arm64', probably
because it does not build-depend on any architecture-independent package.
Of course, cross-compiling pure Java packages is not very useful, but packages
that contain Java and architecture-dependent code cannot be cross-compiled
either.

I have now marked the package as unstable and assume that the MagicSFver2.sf2
file can be redistributed under the LGPL-2.1+ license. I'm not sure if this is
legitimate; please advice.
