Comment 5 for bug 1598371

yes if not set the biendian it will not build .
but i have the feeling the issue is here
ifeq ($(DEB_HOST_ARCH),ppc64)
PTR64=1

i didnt set it because ubuntu on ppc is 32bit, kernels only are 64bit.
and this make issue on libsdl too.
 we are waiting the 64bit migration like is on fedora an suse that are full 64bit (kernel and os)

I suggest to set PTR64=0 on ppc64 too like on powerpc

I forget to mention before, my machine is a ppc64 e5500 P5020
