Hi,
On powerpc64le-linux, using Guix commit
45dd2b4505095d24e253bd62d74474cad135cf3b (the current tip of
core-updates), texlive-latex-base fails to build because the engine
"luajithbtex" is missing:

Previously, we have disabled luajittex because "LuaJIT is not ported to
powerpc64le* yet":

The attached patch fixes the issue. However, I'm curious about a few
things, so I would welcome any input others might have:
- Is it a problem to disable LuaJIT-related things? Based on what I've
found on the Internet, I think it's fine to disable LuaJIT. It looks
like luatex and luatexhb are preferred in most cases. It seems that
luajittex and luajithbtex alternatives do essentially the same thing
as their luatex and luahbtex counterparts, but they run Lua using
LuaJIT (just-in-time compilation capability) instead of the regular
Lua. In their "Short report on the state of LuaTEX, 2020", Luigi
Scarso wrote that luajittex and luajithbtex "should also be considered
a research tool in digital typesetting" [1]. So I don't think we lose
much by disabling it, especially if it isn't supported on powerpc64le.
- Will LuaJIT ever support the powerpc64le architecture? Until it does,
I guess we can't use LuaJIT on powerpc64le at all, not just for
TeX-related stuff.
- Is it correct to add "mfluajit" to the disabled-formats list, like I
do in my patch? It sounds like "mfluajit" is a related to "metafont",
but I don't yet really understand what that means. Is it an engine
like luajit? Is it correct to include mfluajit in the list of formats
to disable in fmtutil.cnf when running fmtutil-sys? I am totally
unfamiliar with these tools, so I have no idea. Perhaps it makes no
sense to include mfluajit here, even if maybe it is benign to do so.
If any TeX wizards out there can clarify this for me, I'd be happy to
adjust the patch as needed.
