Ahh, now we are getting somewhere.

I'm using GCC 4.4.4 and it builds strongswan with the following flags:
"-march=geode -Os -mmmx -m3dnow -pipe -ggdb"

GCC is installed on another system that builds the packages for the
system (since the geode cpu is a bit slow to build a system on) -
could it be that GCC itself is built for another CPU, and that it
somehow embeds some of it into strongswan, causing it to have
instructions not supported by this CPU?
