[Portable][Linux] Architecture detection fail
Hello everyone. This isn't really a big issue, but I had to use a version 5 (precisely 5.0.451.0) of GeoGebra on Linux in order to export an animation to GIF.
The issue is that in the Portable version there is a launcher bash script geogebra-portable which detects the system architecture via the arch command, while using uname it would be compatible with nearly every linux distro.
However, this issue is not present in version 6, so I think it affects only a small fraction of users who need to swap between 6 and 5 versions for some reason..
