If you are inexperienced, you should probably not yet be using ~ppc 
in your ACCEPT_KEYWORDS.  :)  But removing it now would just create 
a lot of unneeded downgrading, so leave it for now.

A differing -mcpu and -mtune?  Are you _sure_ that is okay?

Anyhow, 'man gcc' says that -mpowerpc-gfxopt is overridden by -mcpu, 
so that one flag is pointless.  Why not remove everything that's 
not absolutely necessary, and just put "-O2 -pipe -mcpu=7400"?  
Forget about tuning for a moment, first get a working system.
