I thought sth like that. Thanks for all your answers.
@ptitSeb: Yeah, I thought about that. Besides compile time and memory/storage restrictions, it's also like I mentioned: I usually don't carry my Pandora to work everyday (I know, a crime in itself), so it isn't handy most of the time when I find time to code sth extracurricular. But that would be the goto option. Or I start to really get into the intrinsics of cross-compiling... the script you mention should help to cut some Pandora-specific corners...
