LuaJIT: don't apply ppc64 patchset for ppc (breaks JIT)
There is something in the ppc64 patch that breaks 32-bit ppc in some scenarios (it appears to work but segfaults e.g. when building neovim). So until that is investigated and fixed, conditionalize this.

A patch file from https://github.com/void-linux/void-packages/pull/15328.patch is attached
