[Andreas Jochens] Bug#300368: emacs21: FTBFS (ppc64): Please add support for the ppc64 architecture

[Jérôme Marant]

Hi,

I've just received this patch porting Emacs to the ppc64 architecture.
I have no idea whether this is the right way to do it; maybe someone
will be able to improve it.

Cheers,
