This is what appears to have happened.

1) A change was made to automate the version of triton used in builder.
As part of this change, the builder constraints versions of triton were
removed. At this time, the version of triton was 3.2.0 for Spyre.

2) In builder, the spyre torch version was moved to 2.7.1 which required
triton-3.3.1.

3) An issue was found with the code in step 1. The code was reverted and
RESET the version of triton to 3.2.0 – it should have been set to
3.3.1. Unfortunately no one noticed.

4) While adding s390x support we noticed that triton-3.2.0 was being
built. I made the changes here not understanding that steps 1-3 had
happened (and FWIW, I don't think anyone else would have noticed
either). These changes are a mistake and triton 3.2.0 is really
unused.

These changes made in AIPCC-6028 should be reverted.
