A refinement of the existing powerpc-unknown-linux-gnuspe sample.
Applied, thank you!

Why not use 4.3.2, now it is available?

Maybe we should then be able to add a comment file for each sample, where
we could put this stuff, and it would get displayed when recalling the
sample, the same way EXPERIMENTAL is tested.

I personaly have no objection to using EXPeRIMENTAL features in samples, as
long as it is absolutely needed, which is the case. EXPERIMENTAL is tested
for, and a big fat warning is orinted, so the user knows.
