improve the linux tarball
Currently the linux bundle provides an ELF file that is dynamically linked. This is all well and nice (at least no need to install flatpack, this would have been a stopper for me) but this is likely to break randomly (depends on distro version). I would suggest to use static linking as much as possible, but I know this is not trivial (another solution to have something reasonably portable without requiring user to install lot of things on system are appimages, but they do imply the installation of fuse, so I think it's less nice).
