s390 doesn't have working llvm, so llvmpipe isn't an option. softpipe
might be more featureful but classic swrast is faster. s390x has working
llvm so we can build llvmpipe there.
ppc doesn't have working llvm either (so give it classic swrast too),
but at least it has a PCI bus you could maybe plug things into. Build
gallium nouveau and r300 there, they might not work very well but at
least PowerPC Macs had cards of that vintage. For ppc64 and ppc64le,
build the gallium drivers corresponding to PCIE cards, and llvmpipe.
For all of the above, don't build Vulkan drivers yet. radv should in
principle Just Work on ppc64le, but that's true of aarch64 too, and
we're not building radv by default there yet either.
