NOTE: on big-endian arches (ppc64 and s390x) there are also 67 test errors, but I'll open a separate issue for that.

@mtiberti @wouterboomsma can you have a look at the test outputs here and give us some insights into how bad these failures in the ENCORE tests are?

These are on architectures that we do not officially support but perhaps these failures point to some subtle bugs?

Re-opening because we didn't address s390x. Is this something we want to target? We can add it to our Travis cron matrix, but do we actually have a reasonable expectation that any of our users are using IBM Z machines?

As far as I'm aware there's not a single such machine in the top500, and I can't think of any academic cluster that has one either.

Unless there's a reasonable case for it, I think it might be best to just say we don't cover it?

I'm closing this as a stale issue. Unless someone has a reasonable expectation that MDAnalysis needs to be run on IBM Z then supporting s390x really isn't necessary.

If I'm wrong, please do re-open or open a new issue.

This is not about s390x only. It's about test failures on four non-x86_64 arches and I'd argue at least aarch64 has become relevant now that Apple M1-based machines are out. I'll try to run a fresh build of the latest MDAnalysis source on all arches in Fedora and check what the current status is.

I'm happy to re-open temporarily but MDA has minimal support (we can't guarantee optional dependencies) for non-M1 aarch64 and ppc64le since 2.0.

Note: support for M1 is not happening until CI providers have M1 runners available.

BLD: improve M1 build support

* the changes here allow me to build MDAnalysis and its
dependencies on an M1 Mac on the gcc compile farm using
`python3 -m pip install --user .`

* the full test suite passes, except for 1 extra `xfail`
I've added in here--which is also documented by gh-1389
