Actually I'm not so sure I should apply my fix, my thoughts from
#openmoko-cde...@freenode:
<TAsn> JaMa, btw, jama, thinking about it. It's bitbake's job to strip
stuff, so it must be a config option, it can't be possible we'll have to do
it for every package. If so, we'll probably need to change a global config
and add there do_pacakge_(regular not -dbg)_prepened or something similar.
Though as I said, it's ugly and there's probably a way.
JaMa and I will investigate more about this topic, this is really troubling
though as this wastes huge amount of hd space and also a lot of ram (and
probably cpu) for no apparent reason.
