[gentoo-alt] [RFC] build some more deps before stage3 main show

[Etienne Buira]

Hi,

I came across build failure, where wget were missing. Although it's part
of @system, it is probably needed to build @system itself. But might
better fit in stage2, and used from there.

Things are more complicated about diffutils, as merging ncurses reported
many errors (because missing cmp, and the same script also needs sed,
which is already there in this case).
I did not assess how serious the consequences were if ncurses is built
without it, but builds that goes without errors tend to work better than
with.
I don't know if the correct fix is just to prebuild it here, or add
diffutils and sed as BDEPS for ncurses (i did not assess the potential
for circular deps either).

Any thoughts?
