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

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

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