I took out the unrelated patch to texlive-bin and pushed the part for
texlive-texmf.

Subject: [PATCH] gnu: texlive-texmf: Disable LuaJIT engines on powerpc64le
Date: Mon, 16 Aug 2021 16:46:33 -0300

LuaJIT isn’t ported to powerpc64le. ‘texlive-latex-base’ already disables
them, so just do the same in texlive-texmf.

Fix suggested by Mathieu Othacehe <othacehe <at> gnu.org>.

* gnu/packages/tex.scm (texlive-texmf)[arguments]<#:phases>{texmf-config}:
Disable LuaJIT engines when building for powerpc64le.
---

Hello,

This fixes the build of ‘texlive-texmf’ on powerpc64le. It was failing
with these errors:

  fmtutil [ERROR]: not building luajittex due to missing engine: luajittex
  fmtutil [ERROR]: not building luajithbtex due to missing engine: luajithbtex

Thank you very much to Mathieu for his help in making  this work.
