Can you jdh or anyone with a similar setup try to run the following two
binaries? Run with '--help' only, other than that not much works.

https://github.com/vlasakm/mmtex/releases/download/cross-test/ltex-aarch64-linux-gnu.2.28
https://github.com/vlasakm/mmtex/releases/download/cross-test/ltex-aarch64-linux-musl

If I didn't mistake the architecture, these should work. At least I can
confirm that the second (fully statically linked) one works on my x86_64
linux with:

chmod +x ./ltex-aarch64-linux-musl
qemu-aarch64 ./ltex-aarch64-linux-musl --help

The above are cross compiled (debug) builds of very stripped down
version of LuaTeX, that I have been experimenting with. They won't solve
the immediate problem, but the cross compiling procedure could be used
to generate luametatex binaries for this target until a better option is
available. Of course, depending on whether it even works. :)
