needs suggestion on LuaJit's IBM architecture dilemma

Hi folks,

I learned in disappointment after becoming LuaJit uploader that
the LuaJit upstream behaves uncooperatively especially for IBM
architectures [1]. IIUC, the upstream has no intention to care
about IBM architectures (ppc64el, s390x).

The current ppc64el support on stable is done through cherry-picked
out-of-tree patch. And I learned that the patch is no longer
functional[2] for newer snapshots if we step away from that
ancient 2.1.0~beta3 release.

However, architectures like amd64 needs relatively newer version[3],
while IBM architecture still has demand luajit[4] (only the
ancient version will possibly work on IBM archs).

I'm looking for suggestions on what to do next:

option 1:
  drop IBM architectures that the upstream cannot support
  from src:luajit, and provide archs like amd64 with relatively
  newer snapshot versions[5].
  and package reliable alternatives (if any) for IBM archs.
option 2:
  use latest source for amd64 architecture, and rollback the
  source specifically for IBM architectures to keep it
option 3:
  rollback to the ancient stable release and screw it
option 4:

[5] Yes ... the upstream do not release anymore.
