My arch-dependency test is a little different : "will it work on any
arch". So a shell script that call an arch-specific binary is not
arch-independent in my book (unless the arch-specific binary is sure to
be present on all supported arches, and that's stretching it)

I don't want to expose useless files to users. Unless you find a way to
make sure jni stuff in /usr/share will always have the needed support
in /usr/lib*, I'd rather segregate it in arch-dependent parts.

This is the big one
