Hello

I'm trying to port NetBSD to the GameCube (but don't expect something big
right now). So far, I have gathered code from other ppc architectures,
removed all the I could from it, and made a minimalistic kernel config
file. So I've got something that builds. Now I'm trying to set the entry
point to 0x80003100, but the building fails. Some help would be very
appreciated. Below are the details :
