Bug#798652: scilab: scilab doesn't work on arm64 either

[Edmund Grimley Evans]

There's the same problem on arm64:

$ /usr/bin/scilab
Could not find the Java configuration for the model <aarch64>. Please
contact us on http://bugzilla.scilab.org
/usr/bin/scilab-bin: error while loading shared libraries: libjava.so:
cannot open shared object file: No such file or directory

(However, getfem++ was built on arm64.)
