But then I was using (based on what many users reported when we
started providing the binaries long time ago):
    ppc*|powerpc|power*|Power*) UNAME_PROCESSOR="powerpc" ;;
which covers this as well (without the 64-bit powerpc about which I
don't know anything at all).

And if in doubt, one could use "uname -m" for distingushing between
i386/x86_64 and if the value is neither i*86 nor x86_64, one could
double-check the value of "uname -p" for dealing with PowerPC.
